3-to-8 line decoder, demultiplexer with address latches; inverting

The 74HC137D is a high-speed CMOS decoder/demultiplexer manufactured by NXP Semiconductors.

Specifications:

  • Logic Family: 74HC
  • Function: 3-to-8 line decoder/demultiplexer
  • Operating Voltage: 2.0V to 6.0V
  • Output Current: ±5.2mA
  • Propagation Delay: 18ns (typical at 5V)
  • Input Capacitance: 3.5pF
  • Operating Temperature Range: -40°C to +125°C
  • Package: SOIC-16

Descriptions:

The 74HC137D is a decoder/demultiplexer with three binary address inputs (A0, A1, A2) and an active-low enable input (E1, E2, E3). It decodes the input and activates one of the eight active-low outputs (Y0-Y7).

Features:

  • 3-to-8 Line Decoding/Demultiplexing
  • Active-Low Outputs
  • Multiple Enable Inputs for Flexible Control
  • Low Power Consumption
  • Compatible with TTL Levels
  • ESD Protection (HBM > 2000V, MM > 200V)

This IC is commonly used in digital systems for address decoding, data routing, and memory selection.
