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
) 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
) 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
output and the D
/CET input
means that one interconnection from one stage to the next
higher stage serves as the link for multistage counting or
shift-up operation. The individual Preset (P
n
) inputs are used
to enter data in parallel or to preset the counter in program-
mable counter applications.AHIGH signal on the Master Re-
set (MR) input overrides all other inputs and asynchronously
clears the flip-flops. In addition, a synchronous clear is pro-
vided, as well as a complement function which synchro-
nously inverts the contents of the flip-flops.All inputs have 50
k
pull-down resistors.
