SN74LVCR2245APW

SN74LVCR2245APW is a TI device in the SN74LVCR family. It is a high-speed, low-voltage 20-bit buffer/driver with tri-state outputs, designed to buffer and isolate a wide data bus in CMOS systems.
Key points:
- 20 total buffered I/O lines (buffers a wide data/address bus).
- 3-state outputs controlled by enable signals (OE), enabling or disabling the entire outputs.
- Single-supply operation in the low-voltage CMOS range (about 1.65 V to 3.6 V).
- Low power consumption and fast propagation suitable for buffering in data paths, memory interfaces, and backplanes.
- APW suffix indicates a particular TI package option (20-pin) for this part.
Note: For exact pinout, drive strength, timing parameters, and full operating conditions, refer to the SN74LVCR2245APW datasheet. This provides the authoritative specifications and recommended usage.

Equivalent parts are other 20‑bit buffer/line drivers with 3‑state outputs in the LVCR family. Known equivalents:
- Nexperia (formerly Philips): 74LVCR2245
- ON Semiconductor: MC74LVCR2245
Note: verify pinout, voltage, and package (APW) compatibility; some vendors use different suffixes.

Pin count: 20 pins.
Function: Dual 4-bit bidirectional bus transceiver with 3-state outputs (A0–A3 to B0–B3). Features direction control (DIR) to select data flow and output enable (OE) to place the outputs in a high-impedance state.

- Manufacturer: Texas Instruments (TI).
- Company type: American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other semiconductor devices; headquartered in Dallas, Texas.

- Level shifting between different voltage domains (e.g., 1.8/2.5V to 3.3/5V)
- Bidirectional bus buffering/translation for data and address lines
- I/O expansion for microcontrollers, FPGAs, ASICs
- Memory and peripheral interfaces (RAM/FLASH) requiring buffered, wide data buses
- High-speed digital backplanes and signal integrity improvements
- Automotive and industrial electronics needing robust tri-state buffering and isolation
Note: SN74LVCR2245APW is a high-density, low-voltage, bidirectional buffer/transceiver suitable for wide-bit bus applications.

PW suffix indicates a TSSOP package. SN74LVCR2245APW is in a 24-pin TSSOP (Plastic Thin Shrink Small Outline) package.
