SN74LVC1G240DBVR

Texas Instruments · Buffer/Driver/Transceiver · SOT-23-5

SN74LVC1G240DBVR from Texas Instruments, in a SOT-23-5. 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 OE input Active-low output enable. When high, the Y output is placed in a high-impedance state. Tie to VCC through a pullup resistor to retain high-impedance during power up/down; VIH depends on VCC (e.g. 2V min at VCC=3-3.6V).
2 A input Logic data input. Accepts input voltages up to 5.5V regardless of VCC, enabling down-translation. Propagation delay to Y is 3.7ns max at 3.3V (CL=15pF).
3 GND power_in Ground reference pin. Continuous current through VCC or GND is limited to ±100mA absolute maximum.
4 Y tri_state Inverted, 3-state logic output. Drives ±24mA at VCC=3V and up to ±32mA at VCC=4.5V. High-impedance when OE is high.
5 VCC power_in Positive supply. Operating range 1.65V to 5.5V (data retention only down to 1.5V). Quiescent ICC is 10µA max. Bypass with a local decoupling capacitor to GND.
