100336 Low Power 4-Stage Counter/Shift Register
100336
Low Power 4-Stage Counter/Shift Register
General Description
The 100336 operates as either a modulo-16 up/down
counter or as a 4-bit bidirectional shift register. Three
Select (S
n
) inputs determine the mode of operation, as
shown in the Function Select table. Two Count Enable
(CEP
, CET) inputs are provided for ease of cascading in
multistage counters. One Count Enable (CET
) input also
doubles as a Serial Data (D
0
) input for shift-up operation.
For shift-down operation, D
3
is the Serial Data input. In
counting operations the Terminal Count (TC
) output goes
LOW when the counter reaches 15 in the count/up mode or
0 (zero) in the count/down mode. In the shift modes, the TC
output repeats the Q
3
output. The dual nature of this TC/Q
3
output and the D
0
/CET input means that one interconnec-
tion from one stage to the next higher stage serves as the
link for multistage counting or shift-up operation. The indi-
vidual Preset (P
n
) inputs are used to enter data in parallel
or to preset the counter in programmable counter applica-
tions. A HIGH signal on the Master Reset (MR) input over-
rides all other inputs and asynchronously clears the flip-
flops. In addition, a synchronous clear is provided, as well
as a complement function which synchronously inverts the
contents of the flip-flops. All inputs have 50 k
Ω pull-down
resistors.
