It contains two independent 4-bit elements, each with its own output-enable control, making it a straightforward choice for isolating or re-driving address/data buses, control lines, or general-purpose logic signals in mixed-voltage systems. The supply range from 1.65 V to 3.6 V covers 1.8 V, 2.5 V, and 3.3 V logic rails without a level translator, and the 24 mA symmetric drive at both high and low levels handles standard fan-out for CMOS or TTL-compatible loads. ## Supply range and output drive — what they mean for the BOM The 1.65 V to 3.6 V supply window is the headline feature: it lets this single part sit on a 3.3 V backplane while also buffering a 1.8 V sensor or 2.5 V memory interface, without needing a separate translator. The 24 mA output current per pin is enough to drive a standard logic load or a low-current LED, but not a relay coil or high-capacitance bus — stay within the package's total current limit when all eight outputs switch simultaneously. For higher fan-out or longer traces, consider a buffer with stronger drive or add a line driver stage. ## Package and temperature grade Housed in a 20-SSOP (5.30 mm body width), the SN74LVCH244ADBR is a surface-mount part suited for automated assembly. The industrial temperature range of -40°C to 85°C covers most factory-floor, outdoor telecom, and commercial equipment environments, but not extended automotive under-hood or downhole applications — those would need the -40°C to 125°C grade found in some 74LVCH siblings. ROHS3 compliant per the listing. ## Lifecycle and sourcing reality The SN74LVCH244ADBR carries an Active product status, meaning TI continues to manufacture it and there is no announced last-time-buy or end-of-life notice. This is a standard-production part with no unusual supply pressure.","metaTitle":"SN74LVCH244ADBR Buffer, Non-Inverting, 3-State, 20-SSOP","metaDescription":"TI SN74LVCH244ADBR non-inverting buffer with 3-state outputs, 24mA drive, 1.65V-3.6V supply.
