The 74HC157D from Texas Instruments is a high-speed CMOS silicon monolithic integrated circuit designed as a Quad 2-Channel Multiplexer. It achieves high-speed operation comparable to LSTTL while maintaining the low power dissipation characteristic of CMOS technology.
This multiplexer features a wide operating voltage range from 2.0 V to 6.0 V, with a typical propagation delay of 10 ns at 5 V. Its low power consumption is highlighted by a maximum quiescent current of 4.0 µA at 25°C. The device operates across a wide temperature range of -40°C to 125°C.
Functionally, the STROBE input controls the data selection; when held high, all outputs are low, inhibiting data transfer. The SELECT input decodes whether the A or B inputs are transferred to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
The 74HC157D is available in SOIC16 and 48-BSSOP packages, suitable for surface mount applications. Its balanced propagation delays (tPLH ≈ tPHL) make it a reliable choice for digital logic applications requiring efficient data selection and routing.
