GENERAL DESCRIPTION

The ADM1232A is a superior, pin-compatible upgrade for the

MAX1232 and the DS1232LP and DS1232. The ADM1232A

can detect strobe pulsewidths as narrow as 20 ns, making it

compatible with high speed microprocessors. The Analog

Devices ADM1232A is a microprocessor monitoring circuit

that can monitor:

The ADM1232A is available in four different packages:

1. The ADM1232AARM in an 8-lead µSOIC (RM-8).

2. The ADM1232AAN in an 8-lead PDIP (N-8).

3. The ADM1232AARW in a 16-lead wide SOIC (R-16).

4. The ADM1232AARN is an 8-lead narrow SOIC (R-8).
