HEF4029BT Description

Short technical summary and product information.

The HEF4029BT from Phihong USA is a versatile synchronous edge-triggered up/down 4-bit counter. It supports both binary and BCD decade counting modes, controlled by the BIN/DEC input. The counter features a clock input (CP), an active LOW count enable (CE), an up/down control input (UP/DN), and an overriding asynchronous active HIGH parallel load input (PL).

Data can be asynchronously loaded into the counter via the P0 to P3 inputs when PL is HIGH. The counter advances on the LOW to HIGH transition of CP when CE and PL are LOW. The terminal count (TC) output goes LOW when the counter reaches its maximum count in UP mode or minimum count in DOWN mode, provided CE is LOW.

This integrated circuit is available in a 16-lead SOIC package, suitable for surface mounting. Its design makes it suitable for various digital logic applications requiring counting functionality with control over direction and mode.

Key features include parallel data inputs (P0-P3), buffered parallel outputs (O0-O3), and an active LOW terminal count output (TC). The device operates based on edge-triggered clocking and offers asynchronous parallel loading capabilities.
