74VHCT138A
3-to-8 Decoder/Demultiplexer
Features
■ High Speed: tPD = 7.6ns (Typ.) at VCC = 5V
■ Low power dissipation: ICC = 4A (Max.) at TA = 25°C
■ Power down protection is provided on all inputs and
outputs
■ Pin and function compatible with 74HCT138
General Description
The VHCT138A is an advanced high speed CMOS
3-to-8 DECODER fabricated with silicon gate CMOS
technology. It achieves the high speed operation similar
to equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation.
When the device is enabled, 3 Binary Select inputs
(A0, A1 and A2) determine which one of the outputs
(O0–O7) will go LOW. When enable input E3 is held
LOW or either E1 or E2 is held HIGH, decoding function
is inhibited and all outputs go HIGH. E3, E1 and E2 inputs
are provided to ease cascade connection and for use as
an address decoder for memory systems. Protection
circuits ensure that 0V to 7V can be applied to the input
pins without regard to the supply voltage and to the out-
put pins with VCC = 0V. These circuits prevent device
destruction due to mismatched supply and input/output
voltages. This device can be used to interface 3V to 5V
systems and two supply systems such as battery
backup.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number.
