? semiconductor components industries, llc, 2002 july, 2002 rev. 0 1 publication order number: 74alvc16245/d 74alvc16245 low-voltage 1.8/2.5/3.3v 16-bit transceiver with 3.6 vtolerant inputs and outputs (3state, noninverting) the 74alvc16245 is an advanced performance, noninverting 16bit transceiver. it is designed for very highspeed, very lowpower operation in 1.8 v, 2.5 v or 3.3 v systems. the alvc16245 is designed with byte control. it can be operated as two separate octals, or with the controls tied together, as a 16bit wide function. the transmit/receive (t/r n) inputs determine the direction of data flow through the bidirectional transceiver. transmit (activehigh) enables data from a ports to b ports; receive (activelow) enables data from b to a ports. the output enable inputs (oen ), when high, disable both a and b ports by placing them in a high z condition. ? designed for low voltage operation: v cc = 1.653.6 v ? 3.6 v tolerant inputs and outputs ? high speed operation: 3.0 ns max for 3.0 to 3.6 v 3.7 ns max for 2.3 to 2.7 v 6.0 ns max for 1.65 to 1.95 v ? static drive: 24 ma drive at 3.0 v 12 ma drive at 2.3 v 4 ma drive at 1.65 v ? supports live insertion and withdrawal ? i off specification guarantees high impedance when v cc = 0 v 2 ? near zero static supply current in all three logic states (40 a) substantially reduces system power requirements ? latchup performance exceeds 250 ma @ 125 c ? esd performance: human body model >2000 v; machine model >200 v ? second source to industry standard 74alvc16245 2to ensure the outputs activate in the 3state condition, the output enable pins should be connected to v cc through a pullup resistor. the value of the resistor is determined by the current sinking capability of the output connected to the oe pin. marking diagram a = assembly location wl = wafer lot yy = year ww = work week tssop48 dt suffix case 1201 1 48 74alvc16245dt awlyyww 1 48 device package shipping ordering information 74alvc16245dtr tssop 2500/tape & reel http://onsemi.com
