7403 Description

Short technical summary and product information.

The 7403 is a Quad 2-Input NAND Gate integrated circuit manufactured by SESCOCEM. This component features four independent 2-input NAND gates, each with an open-collector output. This open-collector design allows the outputs to directly interface with CMOS, NMOS, and TTL logic families.

 

The 7403 operates with a supply voltage ranging from 4.75V to 5.25V, with a typical operating voltage of 5V. It has a wide operating free air temperature range of 0°C to 70°C. The device exhibits low power consumption, with typical supply currents of 4mA with outputs high and 12mA with outputs low at Vcc=Max.

 

Key electrical characteristics include a high-level output voltage of 2.4V minimum and a low-level output voltage of 0.4V maximum. Propagation delays are specified at 22nS for low-to-high transitions and 15nS for high-to-low transitions under specific load conditions (Cl=15pF, Rl=400R) at 5V and 25°C.

 

This part is supplied in a DIP package. It is noted as 'Not Recommended for New Designs, Use 74LS03'.
