MC14514BDWR2G

MC14514BDWR2G is an Motorola/Onsemi logic device in the MC14514 family. It is an octal buffer/driver with tri‑state (high‑Z) outputs. Eight non‑inverting buffers share a common output‑enable; when OE is active, inputs appear at the outputs; when OE is inactive, all outputs go high impedance. It is intended to buffer digital signals and increase drive/fan‑out while isolating the source from the load.
Key points:
- 8 separate buffers with a single enable control
- Vcc typically 4.5–5.5 V (CMOS/TTL‑compatible inputs)
- Outputs can be tri‑stated for bus sharing
- BDWR2G is a specific RoHS‑compliant surface‑mount package code (exact type depends on the exact datasheet)
Common uses: data distribution, bus buffering, and signal integrity enhancement in digital systems.

MC14514BDWR2G is a 3-to-8 line decoder/demultiplexer with enable. Equivalents include the 74xx138 family: 74LS138 (and 74LS138N), 74HC138, 74HCT138, 74ACT138, CD74HC138, SN74LS138, etc. These from TI/NXP/ON Semiconductor are direct substitutes in logic-decoder applications.

- Pin count: 20 pins (DIP20/SOIC-20)
- Function: Octal buffer/driver (8-bit tri-state buffer) for buffering data/address lines with 3-state outputs.

The MC14514BDWR2G is manufactured by Motorola. Motorola is a multinational American technology company known for electronics and communications equipment; its semiconductor division became Freescale, which was later acquired by NXP Semiconductors.

MC14514BDWR2G is a high‑current CMOS buffer/driver with tri‑state outputs. Typical applications:
- Buffering/isolation of data and address buses in microprocessor/microcontroller systems
- I/O expansion and bus interfacing between logic families
- Driving LEDs/LCD segments and other display elements
- General-purpose line driving and level shifting in digital circuits
- Tri-state bus architectures in embedded, automotive, and industrial electronics
Concise and suitable for interfacing, buffering, and display-driving needs.
