TTL AND-OR-INVERT gate in a 14-pin DIP
The Texas Instruments 7453PC is an AND-OR-INVERT gate implemented in TTL logic, packaged in a 14-lead PDIP (Plastic Dual In-line Package). This is a classic 74xx-series combinatorial logic function: it performs the AND-OR-INVERT operation on its input groups, producing a single active-low output. The PDIP-14 footprint is breadboard- and through-hole-friendly, suiting prototyping, legacy system repair, and low-volume production runs where surface-mount assembly is not available.
Buyers with RoHS-exempt BOM lines or authorized exemptions can proceed; those requiring full RoHS compliance will need to identify a lead-free alternative.
Sourcing posture for the 7453PC
The active lifecycle status means the manufacturer continues to produce the device, so lead times are generally consistent with standard TI TTL logic production runs. For volume BOM commitments, a quote request with target quantity and delivery window is the recommended next step.
