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.
