Four-Bit Universal Shift
Register
MC10H141
The MC10H141 is a four–bit universal shift register. This device is a
functional/pinout duplication of the standard MECL 10K part with 100%
improvement in propagation delay and operation frequency and no increase in
power supply current.

Pin assignment is for Dual–in–Line Package.
For PLCC pin assignment, see the Pin Conversion
Tables on page 6–11 of the Motorola MECL Data
Book (DL122/D).
NOTE:
Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table,
after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit
board and transverse air flow greater than 500 Iinear fpm is maintained. Outputs are terminated through
a 50 ohm resistor to –2.0 volts.
