FEATURES
HEXDFLIP-FLOP SY100S351
DESCRIPTION
The SY100S351 offers six D-type, edge-triggered, master/
slave ip-ops with differential outputs, and is designed for
use in high-performance ECL systems. The ip-ops are
controlled by the signal from the logical OR operation on a
pair of common clock signals (CPa, CPb). Data enters the
master when both CPa and CPb are LOW and transfers to the
slave when either CPa or CPb (or both) go to a logic HIGH.
The Master Reset (MR) input overrides all other inputs and
takes the Q outputs to a logic LOW. The inputs on this device
have 75kΩ pull-down resistors.

Notes:
1. VEE = –4.2V to –5.5V unless otherwise specied; VCC = VCCA = GND
2. tS is the minimum time before the transition of the clock that information
must be present at the data input.
3. tH is the minimum time after the transition of the clock that information
must remain unchanged at the data input.
