Hex Buffer with Enable
MC10H188
The MC10H188 is a high–speed Hex Buffer with a common Enable input.
When Enable is in the high–state, all outputs are in the low–state. When Enable
is in the low–state, the outputs take the same state as the inputs.
This MECL 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.

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 –2.0 volts.
