Quad 2-input AND gate in 14-TSSOP — the 5V glue-logic workhorse
Each of the four independent gates can source or sink 24mA, making this part suitable for driving multiple downstream logic inputs, LED indicators, or relay coil interfaces through a buffer stage. The supply range of 4.5V to 5.5V means it runs directly from a 5V rail without a regulator.
In a 5V system clocked at 50 MHz (20 ns period), a 9 ns path leaves 11 ns for setup and hold — workable for most combinatorial glue logic, but budget it explicitly if the signal passes through two or three gates in series before reaching a flip-flop input.
14-TSSOP footprint — compact but needs a careful layout
Housed in a 14-TSSOP package with 0.173 inch body width and 4.40 mm height, this is a fine-pitch surface-mount part. The 0.65 mm lead pitch means the PCB land pattern must match the supplier's recommended footprint — a 0.30 mm pad width on a 0.65 mm pitch is typical. No exposed thermal pad, so the package's power dissipation is limited to what the leads and board copper can sink; at 24 mA per output driving a 50 pF load at 5V, junction temperature stays well within the -40°C to 85°C operating range.
Active lifecycle, ROHS3 — no sourcing risk for production
