Description
The ST202B, ST202C is a two-driver, tworeceiver device following EIA/TIA-232 and V.28 communication standards. It is particularly suitable for applications where ± 12 V is not available. The ST202B, ST202C uses a single
5 V power supply and only four external capacitors (0.1 µF). Typical applications are in: portable computers, low power modems, interface translation, and battery-powered
RS-232 networks.

Device summary updated.
Modified: Table 1.
Modified: Table 1 on page 1.
Cover image : replaced silhouettes "SOP" and "SOP Large" with SO16
and SO16L respectively.
Features : updated units of transition slew rate (typ.) from 12 V/ms to
12 V/µs.
Moved “Device summary” table to Section 7: "Ordering information"
section. Removed obsolete order codes ST202BD and ST202CTR from this table and added "Markings".
Section 6.2: "SO16L package information" : replaced package outline
and mechanical data.
Section 6.3: "TSSOP16 package information" : added d
imensions “L1” and “aaa”, replaced dimension “K” with “k”, and removed BSC from dimension “e”.
