UC5172
The UC5172 is a single-ended octal line driver designed to meet both
standard modem control applications (EIA232E/V.28), and long line
drive applicati ons (EIA423A/V.10/X.26). The slew rate for all 8 drivers
is controlled by a single external resistor. The slew rate and output levels are independent of the power variations.
The UC5172 has high output current, and current balance for long line
drive applicatio ns. 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.
