概要
Description
The SN74LVC827APW is an 8-bit register/locus device in TI’s SN74LVC family. It stores eight data bits under clock/enable control and provides tri-state outputs, making it suitable for buffering data on a bus or interfacing between voltage domains.
Key points:
- Low‑voltage CMOS device (typical Vcc range ~1.65 V to 3.6 V)
- 8 data inputs and 8 data outputs with an output‑enable (3‑state) control
- Clock or load control enables data capture; outputs can be tri-stated for bus sharing
- Used for data buffering, bus interfacing, address/data latching, and expansion buffering
Packaging: APW is TI’s package code variant; check the datasheet for exact package options (e.g., TSSOP or SOIC) and pinout.
For precise electrical specs (propagation delay, setup/hold times, power, and I/O characteristics), refer to the SN74LVC827APW datasheet. If you want, I can pull in the exact pinout and figures.

Application
SN74LVC827APW is an octal register/latch with 3-state outputs (bus buffer) in the LVC family (low-voltage CMOS). It provides fast data storage and buffering for 8 bits.
Typical applications:
- Latching data from a microprocessor/peripheral to a wider bus
- Address or data latch in memory-mapped systems
- Buffering/retiming signals between clock domains
- Expanding I/O on a shared bus with tri-state isolation
- Simple pipeline/register stages in digital systems and backplanes
Notes: operates on low-voltage levels and supports bus-friendly, high-speed operation.
