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 20ns, making it
compatible with high speed microprocessors. The Analog
Devices ADM1232A is a microprocessor monitoring circuit
that can monitor:
1. Microprocessor Supply Voltage.
2. Whether a Microprocessor has locked up.
3. An External Interrupt.
The ADM1232A is available in four different packages:
1. The ADM1232AARM in an 8-lead
μ
SOIC (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).
