Output drive is symmetric at 4 mA source and 4 mA sink, enough to drive a downstream CMOS input or a low-power LED indicator. Surface-mount mounting is the only option; no through-hole variant exists.","metaTitle":"SN74AUP1T32DCKR OR Gate, 4.4ns, SC-70-5","metaDescription":"Texas Instruments SN74AUP1T32DCKR single 2-input OR gate with Schmitt trigger. 2.3-3.6V supply, 500nA quiescent, 4.4ns at 3.3V.
