NAME
FUNCTION
1, 9, 16, 25, 32
VCC
Positive Supply Voltage. Bypass from VCC to VEE with 0.1F and 0.01F ceramic capacitors.
Place the capacitors as close to the device as possible with the smaller value capacitor closest to
the device.
2
N.C.
No Connection. Internally not connected.

CLKA
Noninverting Differential Clock Input A
4
CLKA
Inverting Differential Clock Input A
5VBB
Reference Output Voltage. Connect to the inverting or noninverting clock input to provide a
reference for single-ended operation. When used, bypass to VCC with a 0.01F ceramic
capacitor.
