What are the key features of GD75232PWR-ND?
- 3-driver / 5-receiver RS-232 transceiver with asymmetric channel split optimized for host-to-peripheral serial port configurations
- Integrated charge-pump capacitors generate ±12 V RS-232 compliant output levels from a single +5 V supply, eliminating external DC/DC converters
- 20-pin TSSOP small-outline package minimizing PCB footprint in space-constrained serial interface modules
- Full RS-232 compliance per TIA/EIA-232 standard for reliable long-cable communication up to 15 m at 20 kbps
What is GD75232PWR-ND used for?
GD75232PWR-ND is ideal for industrial terminals, POS systems, and embedded computing boards that require multiple RS-232 receive channels alongside fewer transmit lines, such as a host processor communicating with several peripheral instruments. It also suits legacy serial port expansion cards and USB-to-serial bridge designs where the RS-232 voltage-level translation must meet full TIA/EIA-232 electrical specifications.

Frequently Asked Questions
How many RS-232 drivers and receivers does GD75232PWR-ND integrate and how does this split benefit system design?
GD75232PWR-ND integrates 3 RS-232 drivers and 5 receivers in a single 20-TSSOP package. The asymmetric 3/5 split is tailored for host systems that transmit on fewer lines (such as TX and RTS) while receiving on more lines (RX, CTS, DSR, DCD, RI), matching a standard 9-pin RS-232 DTE port without wasting unused channels or requiring a second transceiver IC.
Does GD75232PWR-ND require external charge-pump capacitors to generate RS-232 voltage levels from a 5 V supply?
Yes, the GD75232PWR-ND uses an internal charge-pump topology that requires small external capacitors, typically 100 nF to 1 µF per pump stage, to boost and invert the +5 V supply to the ±12 V RS-232 output swing required by TIA/EIA-232. These capacitors are standard 0402 or 0603 ceramic types, keeping the total BOM simple and the PCB footprint small.
What is the maximum data rate and cable length supported by GD75232PWR-ND for industrial serial communication?
Under TIA/EIA-232 electrical specifications, GD75232PWR-ND supports data rates up to 120 kbps over short cables or the standard 20 kbps over cable lengths up to 15 m with typical cable capacitance. For modern applications, slew-rate-controlled variants can further reduce EMI at distances exceeding 10 m, making it suitable for factory automation terminals, barcode scanners, and instrumentation links in electrically noisy environments.
For a compact serial port design, how much board space does the 20-pin TSSOP package of GD75232PWR-ND occupy?
The 20-pin TSSOP package body measures approximately 6.5 mm × 4.4 mm with 0.65 mm pin pitch. Including the required charge-pump capacitors (4 to 6 capacitors at 0402 size), the total solution area is under 100 mm², enabling very compact RS-232 port implementations on single-board computers, PCIe add-in cards, and embedded SBC modules with tight layout constraints.
When should designers choose GD75232PWR-ND over a simpler MAX232 dual-channel transceiver?
Designers should choose GD75232PWR-ND when a full 9-pin RS-232 DTE or DCE port is required, since MAX232 only provides 2 drivers and 2 receivers covering just TX/RX without modem control signals. GD75232PWR-ND's 3-driver / 5-receiver configuration covers all standard handshake lines (RTS, CTS, DTR, DSR, DCD, RI) in a single 20-TSSOP package, reducing chip count by at least 1 additional IC.
