32, 69, 80 V

31 DCLK

Complementary Differential Clock Outputs. Used to synchronize following circuitry: Outputs A0–A7

are valid after DCLK’s rising edge. B0–B7 output data are valid after DCLK’s falling edge (see Figure 1

for output timing information).

Negative Power Supply, -5.2V ±5% nominal

16, 48, 63 N.C.

10 VB

RBS

“B” side negative reference voltage sense (Note 9)

DIV10 Divide by 10 mode. Leave open for normal operation. Selects test mode when grounded.

Positive Power Supply, +5V ±5% nominal

11 TP4 Internal connection, leave pin open.

13 VB

RTS

“B” side positive reference voltage sense (Note 9)

9 VB

“B” side negative reference voltage input (Note 9)

3, 61 CLK

Complementary Differential Clock Inputs. Can be driven from standard 10KH ECL with the following

considerations: Internally, pins 2, 62 and 3, 61 are the ends of a 50Ω transmission line. Either end

can be driven with the other end terminated with 50Ω to -2V. See

B7–B0

AData and BData Outputs. A0 and B0 are the LSBs, and A7 and B7 are the MSBs. AData and BData

outputs conform to ECL logic swings and drive 100Ω transmission lines. Terminate with 100Ω to -2V

(120Ω for Tj > +100°C). See Figures 1–3.
