1. general description the NVT2003/04/06 is a family of bidirectiona l voltage level translators operational from 1.0 v to 3.6 v (v ref(a) ) and 1.8 v to 5.5 v (v ref(b) ), which allow bidirectional voltage translations between 1.0 v and 5 v without th e need for a direction pin in open-drain or push-pull applications. bit widths ranging from 3-bit to 6-bit are offere d for level translation application with transmission speeds < 33 m hz for an open-drain system with a 50 pf capacitance and a pull-up of 197 ? . when the an or bn port is low, the clamp is in the on-state and a low resistance connection exists between the an and bn ports. the low on-state resistance (r on ) of the switch allows connections to be made with minimal propagation delay. assuming the higher voltage is on the bn port when the bn po rt is high, the voltage on the an port is limited to the voltage set by vrefa. when the an port is high, the bn port is pulled to the drain pull-up supply voltage (v pu(d) ) by the pull-up resistors. this functionality allows a seamless translation between higher and lower voltages selected by the user without the need for directional control. when en is high, the translator switch is on , and the an i/o are connected to the bn i/o, respectively, allowing bidirectional data flow between ports. when en is low, the translator switch is off, and a high-impedance state exists between ports. the en input circuit is designed to be supplied by v ref(b) . to ensure the high-impedance state during power-up or power-down, en must be low. all channels have the same electrical characte ristics and there is minimal deviation from one output to another in voltage or propagat ion delay. this is a benefit over discrete transistor voltage translation solutions, since the fabrication of the s witch is symmetrical. the translator provides excellent esd protection to lower voltage devices, and at the same time protects less esd-resistant devices. 2. features and benefits ? provides bidirectional voltage translation with no direction pin ? less than 1.5 ns maximum propagation delay ? allows voltage level translation between: ? 1.0 v v ref(a) and 1.8 v, 2.5 v, 3.3 v or 5 v v ref(b) ? 1.2 v v ref(a) and 1.8 v, 2.5 v, 3.3 v or 5 v v ref(b) ? 1.8 v v ref(a) and 3.3 v or 5 v v ref(b) ? 2.5 v v ref(a) and 5 v v ref(b) ? 3.3 v v ref(a) and 5 v v ref(b) NVT2003/04/06 bidirectional voltage-level tr anslator for open-drain and push-pull applications rev. 4 ? 7 september 2012 product data sheet free datasheet http:///

[1] +10 % to compensate for v cc range and resistor tolerance. 7.4.1 maximum frequency calculation the maximum frequency is totally dependent u pon the specifics of th e application and the device can operate > 33 mhz. basically, the nvt20xx behaves like a wire with the additional characteristics of tr ansistor device physics and should be capable of performing at higher frequencies if used correctly. here are some guidelines to follow that will help maximize th e performance of the device: ? keep trace length to a minimum by plac ing the nvt20xx close to the processor. ? the trace length should have a time of flight less than half of the transition time to reduce ringing and reflections. ? the faster the edge of the signal, the higher the chance for ringing. ? the higher the drive strength (up to 15 ma), the higher the frequency the device can use. in a 3.3 v to 1.8 v direction level shift, if the 3.3 v side is being driven by a totem pole type driver no pull-up resistor is needed on the 3.3 v side. the capacitance and line length of concern is on the 1.8 v side since it is driv en through the on resistance of the nvt20xx. if the line length on the 1.8 v side is long enough there can be a reflection at the chip/terminating end of the wire when the transition time is shorter than the time of flight of the wire because the nvt20xx looks like a hi gh-impedance compared to the wire. if the wire is not too long and the lum ped capacitance is not excess ive the signal will only be slightly degraded by the series resistance added by passing through the nvt20xx. if the lumped capacitance is large the rise time will deteriorate, the fall time is much less affected and if the rise time is slowed down too much the duty cycle of the clock will be degraded and at some point the clock will no longer be useful. so the principle design consideration is to minimize the wire length and the capacitance on the 1.8 v side for the clock path. a pull-up resistor on the 1.8 v side can also be used to trade a slower fall time for a faster rise time and can also reduce the overshoot in some cases. table 5. pull-up resistor values calculated for v ol = 0.35 v; assumes output driver v ol = 0.175 v at stated current. v pu(d) pull-up resistor value ( ? ) 64 ma 32 ma 15 ma 10 ma 3ma nominal +10 % [1] nominal +10 % [1] nominal +10 % [1] nominal +10 % [1] nominal +10 % [1] 5 v 310 341 465 512 1550 1705 3.3 v 197 217 295 325 983 1082 2.5 v 143 158 215 237 717 788 1.8 v 97 106 145 160 483 532 1.5 v 77 85 115 127 383 422 1.2 v 57 63 85 94 283 312 free datasheet http:///
