DESCRIPTION
The UC5172 is a single-ended octal line driver designed to meet both
standard modem control applications (EIA232E/V.28), and long line
drive applications (EIA423A/V.10/X.26). The slew rate for all 8 drivers
is controlled by a single external resistor. The slew rate and output lev-
els are independent of the power variations.
The UC5172 has high output current, and current balance for long line
drive applications. EOS - Output parasitic SCRs powered on and off
are 35V, well above signal levels, allowing protection devices to work.
Inputs are compatible TTL+MOS logic families and are diode protected
against negative transients.
