Quad Bus Driver/Receiver with

Transmit and Receiver Latches

The MC10H334 is a Quad Bus Driver/Receiver with transmit and receiver

latches. When disabled, (OE = high) the bus outputs will fall to –2.0 V. Data to

be transmitted or received is passed through its respective latch when the

respective latch enable (DLE and RLE) is at a low level. Information is latched

on the positive transition of DLE and RLE. The parameters specified are with

25

Ω loading on the bus drivers and 50 Ω loads on the receivers.

• Propagation Delay, 1.6 ns Typical Data–to–Output

• Improved Noise Margin 150 mV (Over Operating Voltage and

Temperature Range)

• Voltage Compensated

• MECL 10K–Compatible

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.

Receiver outputs are

terminated through a 50–ohm resistor to –2.0 volts

dc. Bus outputs are terminated through a 25–ohm

resistor to –2.0 volts dc.

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).
