SA556 Datasheet Dual Precision Timers

Manufacturer: Texas Instruments

Overview: NA556, NE556, SA556, SE556 SLFS023H – APRIL 1978 – REVISED DECEMBER 2024 Nx556, Sx556 Dual Precision Timers.

General Description

The Nx556 and Sx556 devices provide two independent timing circuits of the NA555, NE555, SA555, or SE555 type in each package.

These circuits operate in an astable or monostable mode with external resistor-capacitor (RC) timing control.

The basic timing provided by the RC time constant is controlled actively by modulating the bias of the control-voltage input.

Key Features

  • Two precision timing circuits per package.
  • Astable or monostable operation.
  • TTL-compatible output can sink or source up to 200mA.
  • Active pullup or pulldown 2.
