TL494CN PWM controller IC TEXAS INSTRUMENTS Brand : Texas Instruments PACKAGE - DIP 16 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

The TS3A44159 is a bidirectional 4-channel single-pole double-throw (SPDT) analog switch with two control inputs, which is designed to operate from 1.65 V to 4.3 V. BRAND - TEXAS INSTRUMENTS ts3a44159
