Input Structures

S3053

Two input structures exist in this part; TTL and High Speed, Differential Inputs. The LVTTL Inputs will interface with

any LVTTL outputs. The High Speed, Differential Inputs can be AC Coupled. Therefore, the High Speed, differen-

tial Input buffers are biased at Vcc -0.5V. Refer to Figure 6 for High Speed Differential Input termination.
