74HC138D
1. Functional Description
• 3-to-8 Line Decoder
2. General
The 74HC138D is a high speed CMOS 3-to-8 DECODER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power
dissipation.
When the device is enabled, 3 Binary Select inputs (A, B and C) determine which one of the outputs (Y0 - Y7)
will go low.
When enable input G1 is held low or either G2A or G2B is held high, decoding function is inhibited and all
outputs go high.
G1, G2A, and G2B inputs are provided to ease cascade connection and for use as an address decoder for memory
systems.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
3. Features
(1) High speed: tpd = 16 ns (typ.) at VCC = 5 V
(2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25
(3) Balanced propagation delays: tPLH ≈ tPHL
(4) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
4. Packaging
