Quad 2-input AND gate in a through-hole DIP — what you're getting
The Texas Instruments CD74AC08E is a quad 2-input AND gate from the 74AC family, packaged in a 14-pin PDIP for through-hole mounting. Each of the four independent gates takes two inputs and delivers a standard AND function. This is a part for designs that need a proven, readily available logic gate in a DIP footprint — think legacy industrial control boards, test equipment, breadboard prototypes, or any through-hole assembly where the 14-DIP form factor is already on the PCB. The 24mA symmetric output drive (source and sink) gives it enough muscle to drive multiple CMOS loads or short PCB traces without an external buffer.
Supply range and temperature grade — the deployment envelope
The -55°C to 125°C operating range qualifies it for military, avionics, satellite, and downhole instrumentation — environments where the commercial or industrial temperature grades won't hold. At 125°C junction, quiescent current stays at a maximum 4 µA, so the static power penalty is negligible even in hot enclosures.
Propagation delay and output drive — what the numbers mean for your bus
Output current is rated 24 mA for both high and low states. That drives a standard CMOS load bank or a low-current LED through a series resistor.
Lifecycle and compliance — active, no obsolescence risk
The CD74AC08E is listed as Active in TI's product portfolio and is ROHS3 compliant. There is no NRND notice, no last-time-buy window, and no announced end-of-life. This is a current-production part with standard lead times through the distribution channel — no date-code provenance worries, no surplus-market gamble. For designs that require a pin-compatible through-hole AND gate in a 14-DIP, this is the part to specify. The 74AC family has been in production for decades and TI continues to manufacture it; there is no second-source urgency for an active, widely available logic gate.
