Product Overview
The SN74LVC1G125DBVR is a Texas Instruments single 3-state bus buffer for Signal_Chain use. Its device function is a single line driver with 3-state output, and the output is disabled when the OE input is high. The DBV pinout assigns OE to pin 1, A input to pin 2, GND to pin 3, Y output to pin 4, and VCC to pin 5.
Recommended operating limits support 1.65 to 5.5 V VCC, 0 to 5.5 V input voltage, and 0 to VCC output voltage. Data-retention operation is specified at 1.5 V. The device operates across -40 to 125 °C free-air temperature, with defined input thresholds across 1.65 V, 2.3 V, 3 V, and 4.5 V supply ranges.
The DBV package is SOT-23-5 with a nominal 2.90 mm x 1.60 mm body. Electrical data includes output drive ratings from 4 mA to 32 mA depending on VCC, leakage specifications in microamps, A-to-Y propagation delay over multiple supply and load conditions, and OE-controlled output enable and disable timing.

Procurement Notes
When requesting a quote for SN74LVC1G125DBVR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What function does SN74LVC1G125DBVR provide?
SN74LVC1G125DBVR is a single line driver with a 3-state output. The output is disabled when the OE input is high, allowing the Y output to enter a high-impedance state under OE control.
What supply voltage range is recommended for this device?
The recommended operating VCC range is 1.65 to 5.5 V. The extracted data also specifies 1.5 V for data retention only, separate from normal recommended operating conditions.
What package and pinout does SN74LVC1G125DBVR use?
