SY100S341
SY100S341
DESCRIPTION
The SY100S341 offer eight D-type, edge-triggered flipflops with both individual inputs for parallel operation as
well as serial inputs for bidirectional shifting, and are
designed for use in high-performance ECL systems. Data
is clocked into the flip-flops on the rising edge of the clock.
The mode of operation is selected by two Select inputs
(S0, S1) which determine if the device performs a shift, hold
or parallel entry function, as described in the Truth Table.
The inputs on these devices have 75kΩ pull-down resistors.
Max. shift frequency of 600MHz
Max. Clock to Q delay of 1200ps
IEE min. of –150mA
Industry standard 100K ECL levels
Extended supply voltage option:
VEE = –4.2V to –5.5V
Voltage and temperature compensation for improved
noise immunity
Internal 75kΩ input pull-down resistors
70% faster than Fairchild 300K at lower power
Function and pinout compatible with Fairchild F100K
Available in 28-pin PLCC package

Notes:
1. VEE = –4.2V to –5.5V unless otherwise specified; 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.
