GENERAL DESCRIPTION

The ADM2xxE is a family of robust RS-232 and V.28 interface devices that operates from a single 5 V power supply. These products are suitable for operation in harsh electrical environments and are compliant with the EU directive on EMC (89/336/EEC). The level of emissions and immunity are both in compliance. EM immunity includes 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.

Shutdown and Enable control pins are provided on some of the products. Please refer to Table I.

The shutdown function on the ADM211E disables the charge pump and all transmitters and receivers. On the ADM213E the

NOTES:

*INTERNAL 400k PULL-UP RESISTOR ON EACH CMOS INPUT

**INTERNAL 5k PULL-DOWN RESISTOR ON EACH RS-232 INPUT

charge pump, all transmitters, and three of the five receivers are disabled. The remaining two receivers remain active, thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication. The active receivers can alert the processor which can then take the ADM213E out of the shutdown mode.

Operating from a single 5 V supply, four external 0.1 F capacitors are required.

The ADM207E and ADM208E are available in 24-lead DIP, SO, SSOP and TSSOP packages. The ADM211E and ADM213E are available in 28-lead SO, SSOP and TSSOP packages.

All products are backward-compatible with earlier ADM2xx products, facilitating easy upgrading of older designs.

PIN FUNCTION DESCRIPTIONS

 

 

Mnemonic

Function

 

 

VCC

Power Supply Input: 5 V ± 10%.

V+

Internally Generated Positive Supply (+9 V nominal).

V–

Internally Generated Negative Supply (–9 V nominal).

GND

Ground Pin. Must Be Connected to 0 V.

C1+, C1–

External Capacitor 1 is connected between these pins. 0.1 µF capacitor is recommended but larger capacitors up

 

to 47 µF may be used.

C2+, C2–

External Capacitor 2 is connected between these pins. 0.1 µF capacitor is recommended but larger capacitors up

 

to 47 µF may be used.

TIN

Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kpull-up resistor to VCC

 

is connected on each input.

TOUT

Transmitter (Driver) Outputs. These are RS-232 signal levels (Typically ±9 V).

RIN

Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kpull-down resistor to GND is

 

connected on each input.

ROUT

Receiver Outputs. These are CMOS output logic levels.

EN/EN

Receiver Enable (Active High on ADM213E, Active Low on ADM211E); This input is used to enable/disable the

 

receiver outputs. With EN = Low ADM211E (EN = High ADM213E), the receiver outputs are enabled. With EN

 

= High (EN = Low ADM213E), the receiver outputs are placed in a high impedance state.

SHDN/SHDN

Shutdown Control (Active Low on ADM213E, Active High on ADM211E); Refer to Table II. In shutdown the

 

charge pump is disabled, the transmitter outputs are turned off and all receiver outputs (ADM211E), receivers R1,

 

R2, R3 (ADM213E) are placed in a high impedance state. Receivers R4 and R5 on the ADM213E continue to

 

operate normally during shutdown. Power consumption in shutdown for all parts reduces to 5 µW.
