 555-Timer-ICs

The 555 timer is a highly stable controller capable of producing accurate time delays or oscillation. The 556 timer combines two 555 timers on a single chip. The 555 can be used in countless applications and has three recognised operating modes. In monostable mode the 555 functions as a one-shot or pulse stretcher. Applications include timers, missing pulse detection and bouncefree switches. In astable mode the 555 can operate as an oscillator. Applications include LED and lamp flashers, pulse generation, logic clocks, tone generation, security alarms and Pulse Width Modulation (PWM). In bistable mode the 555 can operate as a flip-flop or changeover. Applications include bouncefree latched switches. The ICM7555 and ICM7556 are improved versions including lower supply current and a wide supply voltage range.

Questions




Question by Ian Simpson | Product code: 82-1200
7th April 2014

QHi, I am looking for surface mount version of the TLC555CP and both the TLC555CD and the TLC555ID look okay. What is the difference between the CD and ID ?
AHi Ian. Thank you for your question. The ID is the industrial temperature range device +40 to 85 degrees. The CD is the standard temperature version 0 to 70 degrees. The difference is only the operation temperature range.

Question by Karlson | Product code: 82-0336
28th May 2012

QDoes the 555 timer come with a chip holder which allows me to solder it onto a PCB?
AThanks for your enquiry. No I'm afraid the chip does not come with a holder, it's sold seperately as product code 22-1720.

A reliable 555 timer chip. I use hundreds of these and find them to be very reliable. Never had one fail. Much better than some of the cheaper 555s being sold by one supplier that I will not name.
