概述
Description
The SN74AVC9112DCH is TI’s part in the 74AVC family: a 12-bit bidirectional buffer/translator with tri‑state outputs, designed for high‑speed, low‑power buffering between two voltage domains or buses.
Key features
- 12-bit bidirectional buffers with 3‑state outputs
- Direction control (DIR) to select data flow between the A and B sides
- Output enable for tri-stating the buffers
- Single-supply CMOS operation in the CMOS voltage range (typical 2.5–5.5 V)
- Package variant indicated by the DCH suffix
Typical uses
- Interfacing different devices on a bus or between voltage domains
- Bus buffering, level shifting, and backplane/interconnect buffering
Note
- Exact pinout, timing, and package details depend on the DCH variant. Consult the SN74AVC9112DCH datasheet for precise specifications.

Equivalent
Equivalent parts depend on the device’s function and supply. 74AVC9112DCH isn’t a common cross-reference. Please share the datasheet or confirm its function (e.g., 12‑bit buffer/transceiver, bidirectional or not, Vcc, package). With that, I can provide exact equivalents from TI, NXP, Renesas, On Semi, etc.
Features
Here are the typical features of 74AVC9112DCH (AVC family; exact specs come from the datasheet):
- 12-bit non-inverting buffer/driver (two 6-bit sections) with tri-state outputs
- Separate output-enable control (3-state) for bus connection/disconnection
- High-speed CMOS (AVC) with low propagation delay and low static/dynamic power
- Wide operating voltage: typically 2.5 V to 5.5 V (TTL/CMOS compatible inputs)
- Ioff power-down protection (no back-powering when Vcc is off)
- TTL/CMOS-compatible input thresholds
- ESD protection on input/output pins
- Suitable for interfacing data buses and level-shifting applications between devices
- RoHS compliant and halogen-free (DCH suffix)
- Available in small-footprint packages (as indicated by DCH variant)
Note: Exact timing, drive strength, and package details should be confirmed in the specific datasheet for your lot, but these are the standard attributes of the 74AVC9112DCH family.
