It operates across a 2V to 5.5V supply range, making it suitable for mixed-voltage bus interfaces where the I/O rails span from 2V logic up to 5V legacy systems. Each output sources or sinks 8 mA, which is the standard drive for the AHC family — adequate for driving a single TTL load or a short PCB trace, but not for high-fanout buses without a buffer stage. The -40°C to 125°C operating range covers automotive under-hood and industrial enclosure environments where ambient temperature swings are wide. ## Cross-reference delta — SN74ABT2245DW vs SN74AHC245PW For a BOM originally using the SN74ABT2245DW, the SN74AHC245PW would require a board spin if the design relies on the higher output drive or the narrower supply tolerance. The package footprint (20-TSSOP vs 20-SOIC) also differs, so the PCB layout must be verified.","metaTitle":"SN74AHC245PW Texas Instruments 74AHC Transceiver, 20-TSSOP","metaDescription":"SN74AHC245PW — Active 8-bit non-inverting transceiver, 2V-5.5V supply, 8mA drive, -40°C to 125°C, 20-TSSOP.
