概述

Description

ICM7555ESA+T is a dual retriggerable CMOS monostable multivibrator (two independent one-shot timers) from Intersil (Renesas). Each channel has its own trigger input and output; the output goes high for a duration set by an external resistor and capacitor. It is a low-power CMOS device with a broad supply range.
Key features
- Two independent, retriggerable timing channels
- Trigger inputs are active-low
- Timing determined by external RC network (pulse width ≈ RC timer)
- Low input current and RoHS-compliant
Common applications
- Pulse stretching and debouncing
- Fixed-width timing pulses and delay generation
- Edge detection and simple timing control in logic circuits
Packaging note
- ESA+T denotes the package code (8-pin) with tape-and-reel option. For exact supply range, timing equations, and pinout, consult the datasheet.

Features

Here are the key features of the ICM7555ESA+T (CMOS 7555 timer):
- 8-pin device, CMOS version of the 555 timer; pin-compatible with NE555
- Modes: astable and monostable operation
- Wide supply voltage: typically 3 V to 18 V
- Very low quiescent current (suitable for battery operation)
- High drive outputs suitable for logic interfacing (can source/sink significant current)
- Internal discharge transistor for timing network
- Trigger and threshold levels at 1/3 and 2/3 of Vcc (with reset input)
- Timing determined by external resistor and capacitor (supports large RC values)
- Improved temperature stability and lower drift vs. bipolar timers
- Packaging variants including 8-pin DIP/SOIC; Tape & Reel availability (ESA+T)
Ideal uses: low-power timers, oscillators, PWM, waveform generation, and delay circuits in battery-powered or space-constrained apps.

Package

An 8-pin surface-mount package (SOIC-8) with Tape & Reel packaging.

Pinout

- Pin count: 8 pins (DIP-8/SO-8 package).
- Function: ICM7555ESA+T is a CMOS timer IC (7555 family), used as a monostable/astable timer or oscillator (equivalent in function to the 555). Pins: 1 GND, 2 TRIG, 3 OUT, 4 RESET, 5 CTRL, 6 THR, 7 DIS, 8 VCC.

Manufacturer

- Manufacturer: Intersil (now part of Renesas Electronics Corporation).
