General Description
The VHCT245A is an advanced high speed CMOS octal
bus transceiver fabricated with silicon gate CMOS tech-
nology. It achieves high speed operation similar to equiv-
alent Bipolar Schottky TTL while maintaining the CMOS
low power dissipation. The VHCT245A is intended for
bidirectional asynchronous communication between
data busses. The direction of data transmission is deter-
mined by the level of the T/R input. The enable input can
be used to disable the device so that the busses are
effectively isolated.
Protection circuits ensure that 0V to 7V can be applied to
the input and output
(1)
pins without regard to the supply
voltage. These circuits prevent device destruction due to
mismatched supply and input/output voltages. This
device can be used to interface 5V to 3V systems and
two supply systems such as battery back up.
