TC74LCXR164245FT
16-Bit Dual Supply Bus Transceiver with Series Resistor
The TC74LCXR164245FT is a dual supply, advanced
high-speed CMOS 16-bit dual supply voltage interface bus
transceiver fabricated with silicon gate CMOS technology.
Designed for use as an interface between a 5-V bus and a 3.3-V
or 2.5-V bus in mixed 5-V/3.3-V or 2.5-V supply systems, it
achieves high-speed operation while maintaining the CMOS low
power dissipation.
It is intended for 2 way asynchronous communication between
data busses. The direction of data transmission is determined by
the level of the DIR input. The enable input (OE) can be used to
disable the device so that the buses are effectively isolated. The
B-port interfaces with the 5-V bus, the A-port with the 3.3-V or
2.5-V-bus.
The 26-
series resistor helps reducing output overshoot and undershoot without external resistor.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

= 6.8 ns (max)
(V
CCB
= 5.0 ± 0.5 V/V
CCA
= 3.3 ± 0.3 V, Ta =
40 to 85°C)
Low power dissipation: I
CC
= 80 μA (max) (Ta =
40 to 85°C)
Symmetrical output impedance: I

Power-down protection is provided on all inputs and outputs.
Allows A port and V
CCA
to float simultaneously when OE is “H”
Latch-up performance: ±500 mA
Package: TSSOP (thin shrink small outline package)
Bidirectional interface between 5 V and 3.3 V or 2.5 V buses
Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pins must have their input fixed by means of pull-up or pull-down resistors.
Weight: 0.25 g (typ.)
