Product details

Quad buffer with 3-state outputs — the board-level bus interface

The four independent buffers share a common supply but have individual output-enable controls, so you can gate each channel separately for bus isolation or multiplexing. Housed in a 14-TVSOP package (4.40mm width), this is a surface-mount logic gate for dense PCB layouts.

2V to 5.5V supply — the voltage-agile buffer

At 2V it still meets the 8mA output drive, so a battery-powered 2.5V MCU can drive a 5V peripheral bus through this part. The 3-state outputs allow multiple buffers to share a data line — common on SPI chip-select or address lines where one driver is active at a time.

Active lifecycle, ROHS3 — no LTB risk

For new designs this means no near-term obsolescence risk; for existing BOMs it supports ongoing production without requalification.

Frequently asked questions

Is SN74AHC125DGVR obsolete or active?

New designs can proceed without near-term supply risk.

Does SN74AHC125DGVR have 3-state outputs?

Yes, each of the four buffers has an independent 3-state output with its own enable control, allowing bus sharing or high-impedance isolation per channel.

What are the differences between SN74AHC125DGVR and SN74AHC125PWR?

Both are functionally identical quad buffers from the same 74AHC family. The difference is the package: the DGVR suffix is a 14-TVSOP (4.40mm width), while the PWR suffix is a 14-TSSOP (also 4.40mm width but different body length and leadframe). Pinout is the same, but the TVSOP is slightly shorter. Verify board footprint compatibility before substitution.
