Description

The CD74HC138, CD74HC238E, CD74HCT138, and CD74HCT238 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. CD74HC238E Features • Select One Of Eight Data Outputs Active Low for 138, Active High for 238• l/O Port or Memory Selector• Three Enable Inputs to Simplify Cascading• Typical Propagation Delay of 13 ns at VCC = 5 V, CL = 15 pF, TA = 25oC• Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads• Wide Operating Temperature Range . . . -55oC to 125oC• Balanced Propagation Delay and Transition Times• Significant Power Reduction Compared to LSTTL Logic ICs
