M74HC157M1R Description

Short technical summary and product information.

The M74HC157M1R from STMicroelectronics is a high-speed CMOS Quad 2-Channel Multiplexer. Fabricated with silicon gate C2MOS technology, this device features common select and strobe inputs. The SELECT input decodes whether the A or B inputs are routed to their corresponding Y outputs. When the STROBE input is held high, data selection is inhibited, and all outputs become low.

Key electrical characteristics include a wide operating voltage range from 2V to 6V. It boasts a high speed with a typical propagation delay of 10ns at 6V and low power dissipation with a maximum ICC of 4μA at 25°C. The noise immunity is high, with VNlH = VNIL = 28% VCC (min). Symmetrical output impedance is characterized by |IOH| = IOL = 4mA (min), and propagation delays are balanced (tPLH ≅ tPHL).

This multiplexer is suitable for various digital applications requiring signal selection and routing. It is compatible with the 74 Series 157 pinout. The device is supplied in a Surface Mount SOP package, designed for efficient integration into electronic circuits.
