SN74LVC1G57DBVR

Texas Instruments · Gates · SOT-23-6

SN74LVC1G57DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 In1 input Schmitt-triggered logic input 1. One of three configuration/data inputs whose combination selects the gate function and drives output Y. Input voltage tolerated up to 5.5 V regardless of VCC.
2 GND power_in Ground reference (0 V). Also serves as a valid logic-low tie point for unused In0/In1/In2 pins when configuring the gate function.
3 In0 input Schmitt-triggered logic input 0. One of three configuration/data inputs whose combination selects the gate function and drives output Y. Input voltage tolerated up to 5.5 V regardless of VCC.
4 Y output Logic output. Drives ±24 mA at VCC = 3.3 V; the logic function it produces from In0/In1/In2 is set by how the inputs are tied (AND, OR, NAND, NOR, XNOR, buffer, or inverter per Table 1).
5 VCC power_in Positive supply, 1.65 V to 5.5 V. Also serves as a valid logic-high tie point for unused In0/In1/In2 pins when configuring the gate function. Recommended decoupling of 0.1 µF ceramic close to the pin.
6 In2 input Schmitt-triggered logic input 2. One of three configuration/data inputs whose combination selects the gate function and drives output Y. Input voltage tolerated up to 5.5 V regardless of VCC.
