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 Ifpm is maintained. Outputs are terminated through

a 50–ohm resistor to –2.1 volts.

APPLICATIONS INFORMATION

The MC10H424 has TTL–compatible inputs, an ECL strobe

and MECL complementary open–emitter outputs that allow

use as an inverting/non–inverting translator or as a differential

line driver. When the common strobe input is at the low–logic

level, it forces all true outputs to a MECL low–logic state and

all inverting outputs to a MECL high–logic state.

An advantage of this device is that TTL–level information

can be transmitted differentially, via balanced twisted pair

lines, to MECL equipment, where the signal can be received

by the MC10H115 or MC10H116 differential line receivers.
