CD54HCT04F3A

The CD54HCT04F3A from Texas Instruments is a high-speed CMOS logic hex inverter designed for military applications. This device contains six independent inverters, each performing the Boolean function Y = A in positive logic. It operates within a wide supply voltage range of 4.5V to 5.5V and is specified for an extended operating temperature range of -55°C to 125°C.

The inverter features TTL-compatible CMOS inputs with a maximum low input voltage (VIL) of 0.8V and a minimum high input voltage (VIH) of 2V. The input current is limited to 1µA. Its outputs are 3-state, capable of sourcing and sinking current up to 5.2mA (IOL max) and -5.2mA (IOH max) respectively. The device supports a fanout of up to 10 LSTTL loads, offering significant power reduction compared to LSTTL logic.

Packaged in a CDIP (J) format, this through-hole component is suitable for various electronic designs requiring reliable logic inversion. The standard speed characteristic, with propagation delays greater than 50ns, makes it appropriate for applications where high-speed switching is not the primary requirement.

This hex inverter is a robust choice for embedded systems, control circuits, and signal conditioning where stable and predictable logic functions are essential within harsh environmental conditions.
