The 74AHCT series provides TTL-compatible input thresholds while maintaining CMOS low-power operation — the device draws minimal quiescent current when the inputs are static, which matters in battery-backed or power-sensitive 5V subsystems. ## Lifecycle and compliance posture The 74AHCT family has broad distributor stocking, so lead times tend to be short for reel quantities.","metaTitle":"SN74AHCT138PW 3:8 Decoder/Demux, 16-TSSOP, 4.5-5.5V","metaDescription":"Texas Instruments SN74AHCT138PW 1x3:8 decoder/demultiplexer, 4.5-5.5V supply, 8mA output drive, -40 to 85°C, 16-TSSOP.
