SN74HCT125D - Quadruple Bus Buffer Gates

Download the SN74HCT125D datasheet PDF. This datasheet also covers the SN74HCT125 variant, as both devices belong to the same quadruple bus buffer gates family and are provided as variant models within a single manufacturer datasheet.

General Description

The SNx4HCT125 contains four independent buffers with TTL-compatible inputs and 3-state outputs.

Each gate performs the Boolean function Y = A in positive logic.

Key Features

  • Operating voltage range of 4.5 V to 5.5 V.
  • High-current can drive up to 15 LSTTL loads.
  • Low power consumption, 80-µA max ICC.
  • Typical tpd = 12 ns.
  • ±6-mA output drive at 5 V.
  • Low input current of 1 µA max.
  • Inputs are TTL-voltage compatible.
  • High-current 3-state outputs drive bus lines or buffer memory address registers 2.
