GENERAL DESCRIPTION
This V.35 chip set consists of two bipolar chips, one
performing a receive function, the other a transmit
function according to the specification requirements laid
down in Appendix 11 of the V.35 ITU-T Recommendation
and Bell 306 modem interface specification.
Typical applications require three transmit and receive
pairs to establish the link between distant DTE’s at data
rates ranging from 48Kbps to 10Mbps. To conserve
power (especially in the transmitter, which requires
approximately 22mA or each output stage to meet ITU-T
specifications), power-down functions are included in
both devices, allowing any of the three receive/transmit
circuits to be disabled. All inputs and outputs are TTL
compatible and designed to offer maximum versatility and
performance.
Both the transmitter and receiver require termination
resistors external to each device, to meet the V.35
specification tolerance.
