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 V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input. It is
also suitable for use over the industrial (
40
C to +85
C) temperature range.
2. Features and benefits
Fully static operation
5 V, 10 V, and 15 V parametric ratings
Standardized symmetrical output characteristics
Operates across the automotive temperature range
40
C to +85
C
Complies with JEDEC standard JESD 13-B
