The HEF4029B from NXP is a versatile synchronous, edge-triggered, up/down 4-bit binary or BCD decade counter. It is designed for digital logic applications requiring precise counting capabilities.
Key features include a clock input (CP), an active LOW count enable input (CE), an up/down control input (UP/DN), and a binary/decade control input (BIN/DEC). It also incorporates an overriding asynchronous active HIGH parallel load input (PL) and four parallel data inputs (P0 to P3). The counter provides four parallel buffered outputs (O0 to O3) and an active LOW terminal count output (TC).
Information on P0 to P3 is asynchronously loaded into the counter when PL is HIGH, independent of the clock. The counter advances one count on the LOW to HIGH transition of CP when CE and PL are LOW. The TC signal goes LOW when the counter reaches its maximum count in UP mode or minimum count in DOWN mode, provided CE is LOW.
This component is available in a 16-lead DIL plastic package, suitable for through-hole mounting.
