Product details

RS232 transceiver with 5/3 channel count — what it means on the board

The Analog Devices LT1138ACG#PBF is an RS232 full-duplex transceiver with five drivers and three receivers in a 28-SSOP package.

250 KBd data rate — margin for legacy and mid-speed links

Rated at 250 KBd, the LT1138ACG#PBF covers the standard RS232 range with headroom for 250 kbps links. The 400 mV receiver hysteresis helps reject noise on longer runs.

Active lifecycle — no LTB pressure for production runs

That means no last-time-buy scramble and no forced requalification for existing designs. For new builds, it qualifies as a standard-shelf part through independent distribution, quoted to order against an RFQ.

Commercial temperature grade — indoor and office equipment only

Rated 0°C to 70°C, this transceiver is specified for commercial environments: desktop peripherals, point-of-sale terminals, telecom rack equipment in climate-controlled rooms, and test equipment.

Frequently asked questions

What is the data rate of LT1138ACG#PBF?

The LT1138ACG#PBF is rated for 250 KBd, which covers standard RS232 rates up to 115.2 kbps with margin for 250 kbps links.

What is the closest functional second-source for LT1138ACG#PBF?

The ADM202JRWZ-REEL is a functional RS232 transceiver but offers only 2 drivers and 2 receivers versus the LT1138ACG#PBF's 5/3 configuration. For a closer channel count match, the ADM241LJRZ provides 4 drivers and 5 receivers, though at 120 Kbps data rate. Neither is pin-compatible — verify footprint before substituting.
