GENERAL DESCRIPTION

The ADM14196E is a robust RS-232 and V.28 interface device

PRELIMINARY

which operates from +5V and ±12V power supplies. It is suitable

for operation in harsh electrical environments and is compliant

with the EU directive on EMC (89/336/EEC). Both the level of

emissions and immunity are in compliance. EM immunity includes

TECHNICAL

DATA

ESD protection in excess of ±15 kV on all I-O lines (1000-4-2), Fast

Transient Burst protection (1000-4-4) and Radiated Immunity

(1000-4-3). EM emissions include radiated and conducted

emissions as required by Information Technology Equipment

EN55022, CISPR22.

All devices fully conform to the EIA-232E and CCITT V.28

specifications and operate at data rates up to 230 kbps.

The ADM14196E is available in 20-pin SO package.

Notes

1. Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referred to ground unless otherwise specified. For current,

minimum and maximum values are specified as an absolute value and the sign is used to indicate direction. For voltage logic levels, the more positive value is designated

as maximum. For example, if -6V is a maximum, the typical value (-6.8V) is more negative.

2. All typicals are given for VCC = +5.0V, V+ = +12.0V, V- = -12.0V, TA = 25OC.

3. Only one driver output shorted at a time.

4. Generator characteristics for driver input: f = 64kHz (128 kbits/sec), tr = tf = 10ns, V

5. Generator characteristics for receiver input: f = 64kHz (128 kbits/sec), tr = tf = 200ns, V

6. If receiver inputs are unconnected, receiver output is a logic high.

7. Refer to typical curves. Driver output slew rate is measured from the +3.0V to the -3.0V level on the output waveform. Inputs not under test are connected to VCC

or GND. Slew rate is determined by load capacitance. To comply with a 30V/µs maximum slew rate, a minimum load capacitance of 390pF is recommended.
