1. general description the 74alvc164245-q100 is a high-performance, low-power, low-voltage, si-gate cmos device, superior to most advanc ed cmos compatible ttl families. the 74alvc164245-q100 is a 16-bit (dual octal) dual supply translating transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. it is designed to interface between a 3 v and 5 v bus in a mixed 3 v and 5 v supply environment. this device can be used as two 8-bit tr ansceivers or one 16-bit transceiver. the direction control inputs (1dir and 2dir) determine the directi on of the data flow. ndir (active high) enables data from nan port s to nbn ports. ndir (active low) enables data from nbn ports to nan ports. the output enable inputs (1oe and 2oe ), when high, disable both nan and nbn ports by placing them in a high-impedance off-state. pins nan, noe and ndir are referenced to v cc(a) and pins nbn are referenced to v cc(b) . in suspend mode, when one of the supply voltages is zero, there is no current flow from the non-zero supply towards the zero supply. the nan outputs must be set 3-state and the voltage on the a-bus must be smaller than v diode (typical 0.7 v). v cc(b) ? v cc(a) (except in suspend mode). this product has been qualified to the automotive electronics council (aec) standard q100 (grade 1) and is suitable for use in automotive applications. 2. features and benefits ? automotive product qualif ication in accordance with aec-q100 (grade 1) ? specified from ? 40 ? c to +85 ? c and from ? 40 ? c to +125 ? c ? 5 v tolerant inputs/outputs for interfacing with 5 v logic ? wide supply voltage range: ? 3 v port (v cc(a) ): 1.5 v to 3.6 v ? 5 v port (v cc(b) ): 1.5 v to 5.5 v ? cmos low power consumption ? direct interface with ttl levels ? control inputs voltage range from 2.7 v to 5.5 v ? inputs accept voltages up to 5.5 v ? high-impedance outputs when v cc(a) or v cc(b) = 0 v ? complies with jedec standard jesd8-b/jesd36 74alvc164245-q100 16-bit dual supply translating transceiver; 3-state rev. 1 ? 14 may 2013 product data sheet
