TEXAS INSTRUMENTS IC

These octal buffers and line drivers are designed to have the performance of the popular ’HC240 series devices and to offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout. BRAND - TEXAS INSTRUMENTS PACKAGE - SOIC 20 DATASHEET

The TLC555 is a CMOS monolithic timing circuit. The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2MHz. Because of a high input impedance, this device supports smaller timing capacitors than those supported by the NE555 or LM555. As a result, more accurate time delays and oscillations are possible. Power consumption is low across the full range of power-supply voltage. DATASHEET
