Triple 3-input AND gate in 14-TSSOP
The SN74HC11PWR is a triple 3-input AND gate from Texas Instruments' 74HC series, packing three independent AND gates into a 14-TSSOP package. Each gate accepts three inputs and delivers a standard CMOS output capable of sourcing or sinking 5.2 mA, which is enough to drive a downstream logic input or a low-power LED indicator directly. The 2V to 6V supply range means it can sit on a 3.3V or 5V rail without a level translator, and the -40°C to 85°C operating range covers most industrial and commercial enclosures.
Switching speed and static power
Propagation delay is 17 ns max at 6V with a 50 pF load — fast enough for most control logic and sensor gating in a PLC I/O module, where the scan cycle is typically in the millisecond range. Quiescent current sits at just 2 µA max, so the gate draws negligible power when the outputs are static — a useful trait in a 24/7 powered panel where every milliamp of idle current adds up across hundreds of gates. The input logic thresholds scale with supply: low level is 0.5V to 1.8V, high level is 1.5V to 4.2V across the 2V-6V range, ensuring clean switching with standard CMOS or TTL drive levels.
Package and board integration
Housed in a 14-TSSOP (4.40 mm wide body, 0.65 mm pin pitch), the SN74HC11PWR fits a tight PCB layout where board space is at a premium — common in multi-channel I/O cards or compact sensor interface modules. Surface-mount assembly with Tape & Reel or Cut Tape packaging options means it flows through standard reflow profiles without special handling.
Lifecycle and compliance
Texas Instruments lists the SN74HC11PWR as Active with ROHS3 compliance, so it remains a current-production part suitable for both new designs and ongoing BOM replenishment.
