Product Overview
The SN74LVC1G34 is a Texas Instruments single buffer gate in the Signal_Chain category. Its positive-logic function is Y = A, so the output follows the input. Recommended operation covers VCC from 1.65 V to 5.5 V, with a 1.5 V data-retention-only supply condition, 0-5.5 V input range, and output range from 0 to VCC.
Input thresholds are specified across supply ranges, from 0.65 x VCC high-level input minimum at 1.65-1.95 V to 0.7 x VCC high-level input minimum at 4.5-5.5 V. Output drive capability is specified from +/-4 mA at VCC = 1.65 V up to +/-32 mA at VCC = 4.5 V. Propagation delay ranges include 1-2.9 ns at 5 V +/-0.5 V with 15 pF load over -40°C to 85°C.
Assembly choices span YFP, YZP, YZV, DPW, DBV, DCK, DRL, DRY, and DSF packages. Pin functions include A input, Y output, VCC, and GND with package-specific pin or ball assignments. Ioff support enables live insertion, partial power-down mode, and back-drive protection.
