Quad MECL-to-TTL Translator
The MC10H125 is a quad translator for interfacing data and control signals
between the MECL section and saturated logic section of digital systems. The
10H part is a functional/pinout duplication of the standard MECL 10K family
part, with 100% improvement in propagation delay, and no increase in
power–supply current.
Outputs of unused translators will go to low state when their inputs are left
open.

NOTES:
1. When VBB is used as the reference voltage.
2. Each MECL 10H series circuit has been designed to meet the 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 linear fpm is maintained.
3. Differential input not to exceed 1.0 Vdc.
4. 150 mVp–p differential input required to obtain full logic swing on output.
5. 1.0 V to 2.0 V w/25 pF into 500
W
.
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).
