Overview
TLC555 CMOS General Purpose Timer DESCRIPTION PIN CONFIGURATION The TLC555 is a highly stable controller capable of producing accurate timing pulses.
With a monostable operation, the time D,P PACKAGE delay is controlled by one external resistor and one capacitor.
GND 1 8 VCC With an astable operation, the frequency and duty cycle are TRIG 2 7 DISCH accurately controlled by two external resistors and one capacitor.
OUT 3 6 THRES This CMOS RC timers improved parameters include low supply current, wide operating supply voltage range, low THRES, TRIG and RESET currents, no crow barring of the supply current during output transitions, higher frequency performance and no requirement to decouple CONT for stable operation.
RESET 4 5 CONT (Top View) FEATURES Exact equivalent in most cases for SE/NE555 Low supply current High speed operation is 500 kHz guaranteed Wide operation supply voltage range is 2 to 18 volts Timing from microseconds through hours Operates in both astable and monostable modes Adjustable duty cycle High output source/sink driver can drive TTL/CMOS APPLICATION Precision Timing Pulse Generation Time Delay Generation Sequential Timing Pulse width modulation Missing Pulse Detector ORDERING INFORMATION Temperature Range -40°C to +85°C Package DIP-8L SOP-8L Pb-Free Orderable Device TLC555P TLC555D Package Qty 50Units/Tube 100Units/Tube June.
