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 levels 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 patible TTL+MOS logic families and are diode protected against negative transients.
