SN74HC257DR Description

Short technical summary and product information.

The SN74HC257DR is a quad 2-input multiplexer designed for general-purpose logic signal routing. It operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and low-voltage systems. The device provides ±6mA output drive at 5V and can drive up to 15 LSTTL loads. Typical propagation delay is 9ns for the 'HC257 variant and 12ns for the 'HC258 variant. Power consumption is minimal with a maximum supply current of 80µA, and input current is limited to 1µA max, ensuring low loading on driving circuits.

 

The multiplexer is available in multiple package options including D (SOIC), N (PDIP), NS (SOP), and PW (TSSOP), supporting both surface-mount and through-hole assembly. The surface-mount packages are suitable for compact PCB designs. The device is commonly used in data routing, signal selection, and bus switching applications in digital logic systems.
