Product details

The Texas Instruments SN74ABT244AN is a dual-element, non-inverting octal buffer with 3-state outputs in a 20-pin DIP package. Each element handles 4 bits, with a combined output drive of 32 mA source and 64 mA sink per channel — enough to drive a heavily loaded backplane or a bank of LED indicators without external line drivers.

Through-hole DIP — rework-friendly, legacy-fit

The 20-DIP (0.300", 7.62mm) package is through-hole, which means it survives multiple rework cycles under a hot-air station without lifting pads — a practical advantage for prototyping, repair, or low-volume builds where a QFN would be a headache.
