It combines two independent AND gates, each with four inputs, in a single 14-TSSOP package. The supply range of 2V to 5.5V lets it operate in 3.3V and 5V systems without a separate level translator — a common need when bridging a 3.3V MCU to a 5V peripheral. ## Propagation delay and output drive — timing closure With a maximum propagation delay of 7ns at 5V and 50pF load, this gate adds negligible latency in a 20 MHz clocked bus. The 12mA source and sink capability means it can drive a standard CMOS input or a small LED indicator without an external buffer — check the fan-out of the downstream load against the 12mA limit. The quiescent current maxes at 20 µA, so the gate draws virtually no static power in a battery-backed supervisory circuit — a coin cell can keep the gate alive for years in standby. ## Active production — no obsolescence risk The 74LV family is a mature, widely second-sourced logic series, so supply risk is low.","metaTitle":"SN74LV21APWR — Texas Instruments AND Gate, 14-TSSOP, 2V-5.5V","metaDescription":"SN74LV21APWR dual 4-input AND gate from TI's 74LV series. 7ns propagation delay at 5V, 50pF. 2V to 5.5V supply. -40°C to 85°C.

For a drop-in replacement in the 14-TSSOP footprint, look at the 74AHC21PW from Nexperia or the 74VHC21PW from onsemi; both share the same pinout and supply range.
