Part Number: MAX3386E

Function: RS-232 TRANSCEIVER WITH SPLIT SUPPLY PIN FOR LOGIC SIDE

Package: SOIC 20 Pin type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The MAX3386E is a three-driver and two-receiver RS-232 interface device, with split supply pins for mixed-signal operations. All RS-232 inputs and outputs are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model. The charge pump requires only four small 0.1-μF capacitors for operation from a 3.3-V supply. The MAX3386E is capable of running at data rates up to 250 kbps, while maintaining RS-232-compliant output levels. The MAX3386E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driver in (DIN) and receiver out (ROUT) logic levels are pin programmable through the VL pin. The MAX3386E is available in a space-saving thin shrink small-outline package (TSSOP).

Features

• VL Pin for Compatibility With Mixed-Voltage Systems Down to 2.5 V on Logic Side
• Low 300-μA Supply Current
• Specified 250-kbps Data Rate
• 1-μA Low-Power Shutdown
• Meets EIA/TIA-232 Specifications Down to 3 V

Applications:

• Hand-Held Equipment
• PDAs
• Cell Phones
• Battery-Powered Equipment
• Data Cables

Part Number: LT1039CN

Function: RS232 Driver/Receiver with Shutdown

Package: DIP, SO 18 Pin Type

Manufacturer: Linear Technology, Analog Devices

Pinouts:

 

Description

The LT1039CN, LT1039 is a triple RS232 driver/receiver that in cludes shutdown. Each receiver will accept up to ±30V input and can drive either TTL or CMOS logic. The RS232 drivers accept TTL logic inputs and output RS232 voltage levels. The outputs are fully protected against overload and can be shorted to ground or up to ±30V without damage to the drivers.

Additionally, when the system is shut down or power is off, the outputs are in a high impedance state allowing data line sharing. Bipolar circuitry makes this driver/receiver exceptionally rugged
against overloads and immune to latchup.

A BIAS pin allows one receiver to be kept on while the rest of the part is shut down.
The LT1039 is also available in the 16-pin version, without shutdown or BIAS pin functions.

Features

1. Operates from ±5V to ±15V Supplies

2. Fully Protected Against Overload

3. Outputs Can Be Driven ±30V Without Damage

4. Three-State Outputs; Outputs Open When Off

5. Bipolar Circuit—No Latchup
