• Manufacturer Part Number: tza3019
• Description: 2.5 Gbits/s Dual Postamplifier With Level Detectors And 2 X 2 Switch
• Manufacturer: NXP Semiconductors

Philips Semiconductors
TTL logic input of selector and inverter
The logic levels are differently defined for positive or
negative logic (see Fig.9). It should be noted that positive
logic levels are inverted if a negative supply voltage is
used.
Outputs as a function of switch input pins S1, S2,
INV1 and INV2
See Tables 1, 2, 3 and 4.
The default value for the switch input pins S1, S2, INV1
and INV2 if not connected, is zero.
