Product Overview
The SN74LVC1G38 is a Texas Instruments single 2-input NAND gate for positive logic. Its logic function is Y = NOT(A x B), and the output is open drain, so output behavior depends on the external pullup arrangement and the specified 0 to 5.5 V output voltage operating range.
The recommended supply range is 1.65 to 5.5 V, with a 1.5 V minimum supply for data retention only. Inputs are specified over 0 to 5.5 V, and high- and low-level input thresholds are defined across 1.65 V to 5.5 V VCC ranges. The device is rated for operation from -40 to +125 °C.
Electrical limits include 10 µA maximum supply current, ±1 µA maximum input leakage, ±10 µA maximum power-off leakage, 3.5 pF typical input capacitance, and 4.5 pF typical output capacitance at 3.3 V. Package choices cover SOT-23-5, SC70-5, SON-6, DSBGA-5, and X2SON-5 footprints for compact logic placement.
