Additional Details

The TC74LCX157FK(EL) operates within a voltage range of 2.0V to 3.6V, making it suitable for a wide range of applications. The inputs are designed to be TTL compatible, allowing direct interfacing with TTL logic levels without the need for additional level shifting circuitry. The device provides a typical propagation delay of 4.5 ns at 3.3V, ensuring fast data selection and routing. The output drive capability of ±24 mA at 3.0V enables the device to drive heavily loaded lines without significant performance degradation.

The SSOP16 (Shrink Small Outline Package) offers a compact footprint, making it ideal for applications where board space is limited. The device is also designed with ESD protection to prevent damage from electrostatic discharge events. The TC74LCX157FK(EL) is typically used in systems where multiple data sources need to be selected and routed to a single destination, such as in data acquisition systems, communication systems, and digital control systems.
