概述

Description

QS3VH257QG isn’t a widely recognized standard part number in public catalogs I know. If it follows the VH-series CMOS logic naming, it would typically be a quad 2‑to‑1 data selector/multiplexer with tri‑state outputs.
What it does (typical for such devices)
- Four independent multiplexers: each channel selects between two data inputs (A and B) using a common select input.
- Output enable (tri-state): outputs can be placed in high-impedance state when enabled.
- Common select and enable pins, plus four data inputs and four outputs (Y0–Y3).
Common characteristics
- CMOS logic, low power.
- Supply voltage usually in the 3.0–5.5 V range.
- Package options: DIP, SOIC, TSSOP, etc.
Typical use cases
- Data routing and bus multiplexing in digital circuits.
- Selecting data paths in microprocessor/microcontroller interfaces.
- Front-end logic for multiplexed address/data lines.
If you can share the manufacturer or a datasheet/link, I can give a precise, device-specific intro and specs.

Pinout

Pin count: 20 pins.
Function: QS3VH257QG is a quad 2-to-1 data selector (multiplexer) with tri-state (3-state) outputs. It uses two select inputs (S1, S0) to route eight data inputs (D0–D7) to four outputs (Q0–Q3), with a single enable input to tri-state all outputs.

Equivalent

QS3VH257QG is a quad 2-to-1 multiplexer with 3-state outputs (74xx257 family). Equivalents include:
- TI: SN74LS257, SN74HC257, SN74HCT257, SN74VHC257
- NXP/Philips: 74HC257, 74HCT257, 74VHC257
- ST: 74HC257
- Onsemi: MC74VHC257
- Toshiba: TC74HC257
These are generally pin-compatible; verify speed, drive strength, Vcc range, and enable polarity in datasheets.
