DESCRIPTION
The 74VCX16245 is a low voltage CMOS 16 BIT
BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and five-layer metal wiring
C
2
MOS technology. It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs.
This IC is intended for two-way asynchronous communication between data buses; the direction of data transmission is determined by DIR input.
Obsolete Product(s) - Obsolete Product(s) the device so that the buses are effectively isolated.
Obsolete Product(s) - Obsolete Product(s) protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
n = 1, 2
All floating bus terminals during High Z State must be held HIGH or LOW.
