This document describes the Toshiba TC4020BP, TC4020BF, and TC4020BFN integrated circuits. These are CMOS digital silicon monolithic devices designed as 14-stage ripple-carry binary counters or dividers. The chips feature an asynchronous clear function where setting the RESET input to 'H' resets all outputs to 'L', regardless of the CLOCK input.
| Number of stages | 14 stage |
|---|---|
| Max. Clock Frequency (Vcc=5V) | 8.0 MHz |
The counter advances its counting stage by the falling edge of the CLOCK input.
It is a 14 stage ripple carry binary counter suitable for frequency dividers, control circuits, and timing circuits.
All outputs become low regardless of the CLOCK input.
The maximum rating for DC Supply Voltage is +20 V.
