The CD74AC00E: Rated for -55°C to 125°C, this gate suits avionics, satellite, downhole instrumentation, and other extended-temperature environments. The 14-DIP package is also easier to hand-assemble and rework in prototype or low-volume production runs.
The CD74AC00E is listed as Active and ROHS3 compliant. There is no end-of-life notice, so it remains suitable for both new designs and ongoing production.
The maximum propagation delay is 7.3ns at a 5V supply with a 50pF load. This timing is fast enough for high-speed bus interfaces and clock distribution in 5V and 3.3V systems.
Yes. The supply voltage range of 1.5V to 5.5V covers 3.3V operation, and the input logic levels (low 0.3V to 1.65V, high 1.2V to 3.85V) are compatible with 3.3V CMOS outputs. No level shifter is needed when interfacing 3.3V and 5V logic.
The SN74LV00APWR is a surface-mount quad 2-input NAND gate with similar speed (7.5ns at 5V) but a narrower temperature range (-40°C to 85°C) and lower output drive (12mA). For a through-hole part with the same pinout and wider temperature range, the CD74AC00E remains the primary choice.
