NA555PE4

Programmable Timers And Oscillators Overview

The NA555PE4 is a precision timer integrated circuit manufactured by Texas Instruments, belonging to the NA555 series. It functions as a single-channel 555-type timer/oscillator capable of producing accurate time delays or oscillation frequencies up to 100 kHz. The device operates within a supply voltage range of 4.5 V to 16 V and draws a typical supply current of 10 mA. It features TTL-compatible outputs with high sink/source currents of ±200 mA. The component is designed for industrial temperature ranges, operating from -40°C to 105°C, and is housed in an 8-pin DIP package.
