CD4532 8 Bit Priority Encoder IC 16 Pin

Description: CD4532 – 8-Bit Priority Encoder IC (DIP-16)

The CD4532 is an 8-input priority encoder with 3-bit binary output, designed using CMOS technology. It accepts 8 active HIGH inputs (D₀ to D₇) and encodes the highest-priority active input to a 3-bit binary code. It includes enable inputs and outputs for easy cascading.

Key Features:

• 8 input lines (D₀ to D₇)

• 3-bit binary output (A₀, A₁, A₂)

• Highest priority given to D₇ (most significant)

• Cascading capability via enable inputs and outputs

• Standard DIP-16 package

• Wide voltage range: 3V to 15V

• Low power CMOS technology

• TTL-compatible

Pin Configuration (DIP-16):

Functional Summary:

• Priority Encoding: If multiple inputs are HIGH, the IC outputs the binary code of the highest-numbered active input.

• Enable Input (EI̅): When LOW, the IC is enabled. When HIGH, all outputs are disabled.

• Enable Output (EO̅): Goes LOW when any input is active and the IC is enabled; used for cascading.

• Group Select (GS): Goes HIGH when the encoder is active and at least one input is HIGH.
