Product Overview
The TLC552 is a Texas Instruments dual LinCMOS timer for Signal_Chain designs requiring timer, trigger, threshold, discharge, and output-drive functions. It is available in SOIC (D)-14 and PDIP (N)-14 package options, giving assembly choices for surface-mount and through-hole layouts.
Recommended operation covers a 1 V to 18 V supply range, with the TLC552C characterized over 0 to 70 °C free-air temperature. Absolute maximum ratings include 18 V supply voltage, input voltage from -0.3 V to VDD, -65 to 150 °C storage temperature, and ESD protection up to 2000 V by MIL-STD-883C Method 3105.2.
Electrical data spans 1 V, 2 V, 5 V, 15 V, and 18 V operation. At 5 V, threshold and trigger levels are 3.3 V typical and 1.66 V typical, respectively, with 340 µA typical supply current. Timing data includes 1% typical initial timing interval error, 0.1 %/V typical supply-voltage sensitivity, 20 ns typical rise time, 15 ns typical fall time, and 1.2 MHz typical astable frequency under the stated test conditions.

Procurement Notes
When requesting a quote for TLC552, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
