SK10/100E131
4-Bit D Flip-Flop
HIGH-PERFORMANCE PRODUCTS
Description
The SK10E/100E131 is a Quad master-slave D-type flip-
flop with differential outputs. Each flip-flop may be
clocked separately by holding Common Clock (CC) LOW
and using the Clock Enable (CE*) inputs for clocking.
Common clocking is achieved by holding the CE inputs
LOW and using CC to clock all four flip-flops. In this
case, the CE* inputs perform the function of controlling
the common clock to each flip-flop.

Individual asynchronous resets are provided (R).
Asynchronous set controls (S) are ganged together in •
pairs, with the pairing chosen to reflect physical chip •
symmetry.
Data enters the master when both CC and CE* are LOW,
and transfers to the slave when either CC or CE (or both)
go HIGH.

NOTES:
1. Datums -L-, -M-, and -N- determined where top of lead
shoulder exits plastic body at mold parting line.
2. DIM G1, true position to be measured at Datum -T-,
Seating Plane.
3. DIM R and U do not include mold flash. Allowable
mold flash is 0.010 (0.250) per side.
4. Dimensioning and tolerances per ANSI Y14.5M,
1982.
5. Controlling Dimension: Inch.
6. The package top may be smaller than the package
bottom by up to 0.012 (0.300). Dimensions R and U
are determined at the outermost extremes of the
plastic body exclusive of mold flash, tie bar burrs,
gate burrs and interlead flash, but including any
mismatch between the top and bottom of the plastic
body.
7. Dimension H does not include Dambar protrusion or
intrusion. The Dambar protrusion(s) shall not cause
the H dimension to be greater than 0.037 (0.940).
The Dambar intrusion(s) shall not cause the H
dimension to be smaller than 0.025 (0.635).

Notes:
1. 10E circuits are designed to meet the DC specifications shown in the table after thermal equilibrium has
been established. The circuit is in a test socket or mounted on a printed circuit board and transverse
airflow greater than 500 lfpm is maintained.
2. The same DC parameter values apply across the full VEE range of –4.2 to –5.5V. 100E circuits are
designed to meet the DC specifications shown in the table where transverse airflow greater than 500 lfpm
is maintained.
3. Within device skew is defined as identical transitions on similar paths through a device.
4. For standard ECL DC Specifications, refer to the ECL Logic Family Standard DC Data
Sheet.
5. For part ordering description, see HPP Part Ordering Information Data Sheet.
