Micrel, Inc.

4-STAGE COUNTER/

SHIFT REGISTER

FEATURES

DESCRIPTION

The SY100S336 functions either as a modulo-16 up/

down counter or as a 4-bit bidirectional shift register and is

designed for use in high-performance ECL systems. Three

Select inputs (Sn) are provided for determining the mode of

operation. The Function Table lists the available modes of

operation. In order to allow cascading for multistage

counters, two Count Enable controls (CEP, CET) are

provided. The CET input also functions as the Serial Data

input (S0) for a shift-up operation, while the D3 input serves

as the Serial Data input for the shift-down operation.

When the device is in the counting mode, the Terminal

Count (TC) goes to a logical LOW when the count reaches

15 for count-up or reaches 0 for count-down. When in the

shift mode, the TC output simply repeats the Q3 output.

The flexiblity provided by the TC/Q3 output and the D0/

CET input allows these signals to be interconnected from

one stage to the next higher stage for multistage counting

or shift-up operations. The individual Presets (Pn) allow

initialization of the counter by entering data in parallel to

preset the counter. A logic HIGH on the Master Reset (MR)

overrides all other inputs and asynchronously clears the

flip-flops. An additional synchronous Clear is provided, as

well as a complement function which synchronously inverts

the contents of the flip-flops. All inputs have 75KΩ pull-

down resistors.
