M74HC42B1R Description

Short technical summary and product information.

The STMicroelectronics M74HC42B1R is a high-speed CMOS BCD to Decimal Decoder fabricated with silicon gate C2MOS technology. It selects one of ten decimal outputs based on a BCD code applied to its four inputs (A-D). This device is pin and function compatible with the 74 Series 42.

 

Key electrical characteristics include a wide operating voltage range of 2V to 6V and a low supply current of 4μA maximum at 25°C. It offers high noise immunity with VNIL and VNIH at 28% VCC minimum, and symmetrical output impedance with |IOH| = IOL = 4mA minimum. Propagation delays are balanced, with tPD typically 14ns at VCC = 6V.

 

The M74HC42B1R is housed in a 16-DIP (0.300", 7.62mm) through-hole package. It operates across a wide temperature range of -55°C to 125°C. All inputs are equipped with protection circuits against static discharge and transient excess voltage, making it suitable for various code conversion, address decoding, and memory selection applications.
