74VHCT244A
Octal Buffer/Line Driver with 3-STATE Outputs
Features
■ High Speed: tPD = 5.9ns (Typ.) at VCC = 5V
■ Power down protection is provided on inputs and
outputs
■ Low power dissipation: ICC = 4A (Max.) @ TA = 25°C
■ Pin and function compatible with 74HCT244
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(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.
Note:
1. Outputs in OFF-State
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number. Pb-Free package per JEDEC J-STD-020B.
