SN74CBTD1G384DBVR

Texas Instruments · Analog Switches, Multiplexers · SOT-23-5

SN74CBTD1G384DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A passive Switch port A of the single FET bus switch, providing a 5-Ω connection to port B when OE is low.
2 GND power_in Ground reference; all unused control inputs must be held at VCC or GND to ensure proper device operation.
3 B passive Switch port B, connected to port A when OE is low; the datasheet describes level shifting from 5-V inputs to 3.3-V outputs across this switch.
4 OE input TTL-compatible output-enable input that disables the switch when high, with VIH of 2 V minimum and VIL of 0.8 V maximum.
5 VCC power_in Supply voltage with a recommended range of 4.5 V to 5.5 V and an absolute maximum of 7 V; an internal diode to VCC provides the level shifting.
