M74HC148M1R Description

Short technical summary and product information.

The STMicroelectronics M74HC148M1R is a high-speed CMOS 8-to-3 line priority encoder. Fabricated using silicon-gate C2MOS technology, it offers high speed performance comparable to LSTTL devices while maintaining true CMOS low power consumption.

 

This encoder converts eight data lines into a three-line (4-2-1) binary (octal) output. It includes cascading circuitry with an enable input (EI) and enable output (EO) for octal expansion without external components. Data inputs are active at the low logic level.

 

Key electrical characteristics include a wide operating voltage range from 2V to 6V, a typical propagation delay of 15 ns at 5V, and a low quiescent current of 4 μA at 25°C. The device is designed for high noise immunity and has an output drive capability of 10 LSTTL loads.

 

The M74HC148M1R is available in an M1R package, suitable for surface mount applications. All inputs are equipped with protection circuits against static discharge and transient overvoltage.
