description

The SN55115 and SN75115 dual differential line

receivers are designed to sense small differential

signals in the presence of large common-mode

noise. These devices give TTL-compatible output

signals as a function of the differential input

voltage. The open-collector output configuration

permits the wire-ANDing of similar TTL outputs

(such as SN5401/SN7401) or other

SN55115/SN75115 line receivers. This permits a

level of logic to be implemented without extra

delay.

The output stages are similar to TTL totem-pole outputs, but with sink outputs, 1YS and 2YS, and the

corresponding active pullup terminals, 1YP and 2YP, available on adjacent package pins. The frequency

response and noise immunity may be provided by a single external capacitor. A strobe input is provided for each

channel. With the strobe in the low level, the receiver is disabled and the outputs are forced to a high level.

The SN55115 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN75115 is characterized for operation from 0°C to 70°C.
