General Description
The VHCT244A 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 VHCT244A is a non-
inverting 3-STATE buffer having two active-LOW output
enables. This device is designed to be used as 3-STATE
memory address drivers, clock drivers, and bus oriented
transmitter/receivers.
Protection circuits ensure that 0V to 7V can be applied to
the input and output
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.
