Product details

Device function and logic family

The 74S153PC is a dual 4-line input multiplexer implemented in Schottky TTL logic, providing two independent 4:1 selector circuits in a single through-hole package. This part belongs to the 74S series, a high-speed Schottky-clamped TTL family that offers faster propagation delays than the standard 74LS series while maintaining TTL-compatible I/O levels.

Lifecycle and compliance status

Note that this device is RoHS non-compliant, so it is intended for applications that are exempt from RoHS requirements or for use in legacy assemblies where lead-bearing solder is permitted.

Package and board integration

Supplied in bulk (tube or tray), the 74S153PC uses a standard through-hole DIP footprint — the same 16-pin layout as other 74S series dual multiplexers — making it a drop-in for existing PCB designs without layout changes.

Frequently asked questions

Can 74LS153 replace 74S153PC?

The 74LS153 is a lower-power, slower-speed variant of the same dual 4-line multiplexer function. It is pin-compatible and can often serve as a replacement where the higher speed of Schottky TTL is not required, but the switching thresholds and propagation delays differ — verify timing margins in your specific circuit before substituting.

What is the function of 74S153PC?

The 74S153PC contains two independent 4-line-to-1-line multiplexers. Each section selects one of four data inputs based on a common two-bit select code, routing the chosen input to the corresponding output.
