Package

The MC14538BCP is typically packaged in a DIP (Dual In-line Package) format, specifically a 16-pin DIP. This package type is suitable for through-hole mounting on printed circuit boards.

Pinout

The MC14538BCP is a dual 4-bit binary to decimal decoder/demultiplexer with a pin count of 16. Its primary function is to decode 4-bit binary inputs into one of 16 possible outputs, allowing it to select one output line based on the binary value presented at the input.
The pin configuration includes:
- 1: GND (Ground)
- 2: A0 (Input)
- 3: A1 (Input)
- 4: A2 (Input)
- 5: A3 (Input)
- 6: E (Enable, active low)
- 7: D0 to D15 (Outputs)
- 8: VCC (Power supply)
When enabled, the decoder activates the output corresponding to the binary value of the inputs, making the MC14538BCP useful in applications like memory address decoding, data routing, and control systems.
