TC74LCX164245FT
16-Bit Dual Supply Bus Transceiver
The TC74LCX164245FT 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.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
Bidirectional interface between 5-V and 3.3-V or 2.5-V buses
High-speed: t

Power-down protection provided on all inputs and outputs
Allows A port and V

to float simultaneously when OE is “H”.
Latch-up performance: ±500 mA
Package: TSSOP (thin shrink small outline package)
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.)
