Output drive is 15 mA sourcing and 24 mA sinking — enough for a loaded backplane or a bank of LED indicators without a buffer. That covers office equipment, lab instruments, and indoor industrial control panels — not engine bays or outdoor telecom cabinets. Supplied on Tape & Reel (TR) with Cut Tape (CT) option. Store the reels in a dry cabinet below 30°C / 60% RH if the bake time on the label is expired — the SOIC body is not moisture-sensitive per JEDEC Level 1, but the reel label tells the story.","metaTitle":"SN74ALS645A-1NSR TI 74ALS Transceiver, 8-bit, 20-SOIC","metaDescription":"Texas Instruments SN74ALS645A-1NSR 8-bit non-inverting transceiver, 3-state outputs, 4.5V-5.5V supply, 15/24mA drive.
