The supplier device package is 20-TSSOP, and the part is supplied on Tape & Reel (TR) with a Cut Tape (CT) option for prototype quantities. ## 5 V logic bus buffering with 3-state control This is a non-inverting buffer with 3-state outputs — two elements each handling 4 bits, giving an 8-bit bus width. The 3-state output lets multiple drivers share a common bus line; when the output enable is deasserted, the outputs go high-impedance and the bus floats. Supply voltage spans 4.5 V to 5.5 V, matching standard 5 V TTL/CMOS rails. Output drive is 8 mA source and 8 mA sink — sufficient for driving a few TTL loads or short PCB traces, but not intended for high-current backplane or cable driving. ## Automotive-grade qualification and temperature range The part belongs to Texas Instruments' Automotive, AEC-Q100, 74AHCT series, meaning it has passed AEC-Q100 stress tests for automotive IC reliability — including temperature cycling, ESD, latch-up, and extended life tests. The operating temperature range is -40°C to 85°C (TA), which covers passenger cabin and under-hood applications that do not exceed 85°C ambient. The 74AHCT logic family is a 5 V, high-speed CMOS series with TTL-compatible input thresholds — it interprets a 2.0 V input as a logic high, so it interfaces directly with older 5 V TTL logic without a level translator.","metaTitle":"TI CAHCT244IPWRG4Q1 Buffer, 20-TSSOP, 5V, AEC-Q100","metaDescription":"Texas Instruments CAHCT244IPWRG4Q1 automotive-grade octal buffer, 4.5-5.5V supply, 8mA drive, 20-TSSOP.

This is adequate for driving standard CMOS loads, short PCB traces, or up to a few TTL gate inputs. For higher current requirements, a bus transceiver with stronger drive should be considered."},{"question":"What is the difference between CAHCT244IPWRG4Q1 and SN74LVTH16245ADGVR?","answer":"The SN74LVTH16245ADGVR is a 16-bit transceiver (8 bits per element, 2 elements) with 32 mA output drive, operating at 2.7 V to 3.6 V supply. The CAHCT244IPWRG4Q1 is an 8-bit buffer (4 bits per element, 2 elements) with 8 mA drive at 5 V.
