100336  
Low Power 4-Stage Counter/Shift Register  
to enter data in parallel or to preset the counter in program-  
mable counter applications. A HIGH 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  
kpull-down resistors.  
General Description  
The 100336 operates as either  
a modulo-16 up/down  
counter or as a 4-bit bidirectional shift register. Three Select  
(Sn) 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  
(D0) input for shift-up operation. For shift-down operation, D3  
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 Q3 output. The  
dual nature of this TC/Q3 output and the D0/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 (Pn) inputs are used
