Multivibrators

The Texas Instruments SN74AHC123ADR is a high-speed silicon gate monolithic integrated circuit. It is a dual single-pole, double-throw analog switch with a wide range of applications in various electronic systems.

Description:

The SN74AHC123ADR is a member of the 74AHC/AHCT family of high-speed CMOS devices. It features two independent single-pole, double-throw (SPDT) analog switches that can handle both AC and DC signals. The device is available in a 16-pin small-outline integrated circuit (SOIC) package.

Features:

1. Dual single-pole, double-throw (SPDT) analog switches
2. Wide voltage range: 2.0V to 6.0V for the SN74AHC123 and 2.0V to 5.5V for the SN74AHCT123
3. High-speed operation: Propagation delay is typically 4.5 ns (typical) for the SN74AHC123 and 15 ns (typical) for the SN74AHCT123
4. Low on-resistance: Typically 45 ohms (typical) for the SN74AHC123 and 100 ohms (typical) for the SN74AHCT123
5. Low input offset voltage: Typically 2 mV (typical) for both devices
6. Low power consumption: Typically 3 mA (typical) for the SN74AHC123 and 4 mA (typical) for the SN74AHCT123
7. Compatible with TTL and CMOS logic levels
8. Available in 16-pin SOIC package
