HD74AC138FPEL is a high-speed CMOS 3-to-8 line decoder/demultiplexer manufactured by Hitachi.

The HD74AC138FPEL is a high-speed CMOS 3-to-8 line decoder/demultiplexer manufactured by Hitachi.

Specifications:

  • Logic Type: 3-to-8 Line Decoder/Demultiplexer
  • Technology: Advanced CMOS (AC)
  • Supply Voltage Range: 2.0V to 6.0V
  • High-Speed Operation: tpd = 6.0ns (typical) at 5V
  • Low Power Consumption: ICC = 4μA (max) at 5V
  • Output Drive Capability: 24mA at 5V
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: Plastic DIP (16-pin)

Descriptions:

The HD74AC138FPEL decodes three binary address inputs (A0, A1, A2) into one of eight mutually exclusive outputs (Y0-Y7). It features three enable inputs (two active LOW and one active HIGH) for flexible control.

Features:

  • Three Enable Inputs: Two active LOW (E1, E2) and one active HIGH (E3)
  • Multiple Input/Output Combinations: Allows cascading for larger decoding applications
  • High Noise Immunity: CMOS technology ensures stable operation
  • Low Propagation Delay: Ensures high-speed performance
  • Wide Operating Voltage Range: Compatible with TTL levels

This device is commonly used in memory decoding, data routing, and demultiplexing applications.

(Note: Always refer to the official datasheet for detailed electrical characteristics and application notes.)
