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 kΩ pull-down
resistors.
