description
The SN55138 and SN75138 quadruple bus
transceivers are designed for two-way data
communication over single-ended transmission
lines. Each of the four identical channels consists
of a driver with TTL inputs and a receiver with a
TTL output. The driver open-collector output is
designed to handle loads up to 100-mA open
collector. The receiver input is internally
connected to the driver output, and has a high
impedance
to
minimize
transmission line. Because of the high driver-
output current and the high receiver-input
impedance, a very large number (typically
hundreds) of transceivers may be connected to a
single data bus.
loading
of
the
The receiver design also features a threshold of 2.3 V (typical), providing a wider noise margin than would be
possible with a receiver having the usual TTL threshold. A strobe turns off all drivers (high impedance) but does
not affect receiver operation. These circuits are designed for operation from a single 5-V supply and include a
provision to minimize loading of the data bus when the power-supply voltage is zero.
The SN55138 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN75138 is characterized for operation from 0
°
C to 70
