Description
The ’HC138, ’HC238, ’HCT138, and ’HCT238 are high-speed
silicon-gate CMOS decoders well suited to memory address
decoding or data-routing applications. Both circuits feature
low power consumption usually associated with CMOS
circuitry, yet have speeds comparable to low-power Schottky
TTL logic. Both circuits have three binary select inputs (A0,
A1, and A2). If the device is enabled, these inputs determine
which one of the eight normally high outputs of the
HC/HCT138 series go low or which of the normally low
outputs of the HC/HCT238 series go high.
Two active low and one active high enables (E1, E2, and E3)
are provided to ease the cascading of decoders. The
decoder’s eight outputs can drive ten low-power Schottky
TTL equivalent loads.
CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
