HEF40193B  
4-bit up/down binary counter  
Rev. 8 — 18 November 2011  
Product data sheet  
1. General description  
The HEF40193B is a 4-bit synchronous up/down binary counter. The counter has a  
count-up clock input (CPU), a count-down clock input (CPD), an asynchronous parallel  
load input (PL), four parallel data inputs (D0 to D3), an asynchronous master reset input  
(MR), four counter outputs (Q0 to Q3), an active LOW terminal count-up (carry) output  
(TCU), and an active LOW terminal count-down (borrow) output (TCD).  
The counter outputs change state on the LOW-to-HIGH transition of either clock input.  
However, for correct counting, both clock inputs cannot be LOW simultaneously. The  
outputs TCU and TCD are normally HIGH. When the circuit has reached the maximum  
count state of ‘15’, the next HIGH-to-LOW transition of CPU will cause TCU to go LOW.  
TCU will stay LOW until CPU goes HIGH again. Likewise, output TCD will go LOW when  
the circuit is in the zero state and CPD goes LOW. When PL is LOW, the information on  
D0 to D3 is asynchronously loaded into the counter. A HIGH on MR resets the counter  
independent of all other input conditions. The counter stages are of a static toggle type  
flip-flop.  
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS  
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.  
2. Features and benefits  
Fully static operation  
5 V, 10 V, and 15 V parametric ratings
