3-to-8 Line Decoder

The TC74ACT138 is an advanced high speed CMOS 3-to-8

LINE DECODER fabricated with silicon gate and double-layer

metal wiring C2MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

This device may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

When the device is enabled, 3 Binary Select inputs (A, B and

C) determine which one of the outputs ( 0

Y - 7

Y ) will go low.

When enable input G1 is held low or either

A

or

2B

G

is

held high, decoding function is inhibited and all outputs go high.

G1,

G

, and

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.

Features

• High speed: tpd = 6.0 ns (typ.) at VCC = 5 V

• Low power dissipation: ICC = 8 μA (max) at Ta = 25°C

• Compatible with TTL outputs: VIL = 0.8 V (max)

VIH = 2.0 V (min)

• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)

Capability of driving 50

Ω

transmission lines.

• Balanced propagation delays: tpLH ∼− tpHL

• Pin and function compatible with 74F138

Note:

xxxFN (JEDEC SOP) is not available in

Japan.
