ALD4302A/ALD4302  
QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER  
GENERAL DESCRIPTION  
APPLICATIONS  
The ALD4302A/ALD4302 is a monolithic high performance quad voltage  
comparatorbuiltwithadvancedsilicongateCMOStechnology. Itfeatures  
veryhightypicalinputimpedanceof10 ;lowinputbiascurrentof10pA;  
fast response time of 120ns; very low power dissipation of 150µA per  
comparator; and single (+5V) or dual (±5V) power supply operation.

• Multiple limit window comparator  
• Power supply voltage monitor  
• Photo-detector sensor circuit  
• High speed LED driver  
• Oscillators  
• Battery operated instruments  
• Remote signal detection  
• Multiple relay drivers  
Theinputvoltagerangeincludesground, makingthiscomparatoridealfor  
single supply low level signal detection with high source impedance. The  
outputs can source and sink current, allowing application flexibility, and  
canbeusedineitherwired-ORconnectionwithoutpullupresistororpush-  
pull configuration. The ALD4302A/ALD4302 can be used in wired-OR  
connections with other open drain circuits such as the ALD2301 and  
ALD2303 voltage comparators.  
PIN CONFIGURATION  
The ALD4302A/ALD4302 is ideal for a great variety of precision voltage  
comparator applications, especially low level signal detection circuits  
requiring low standby power, yet retaining high output current capability.

• Low supply current of 150µA each comparator  
• Extremely low input bias currents -- typically 10pA  
• Virtually eliminates source impedance effects  
• Low operating supply voltage of 4V to 10V  
• Single (+5V) and dual supply (±5V) operation  
• High speed for both large and small signals -  
120ns for TTL inputs and 400ns for 5mV overdrive  
• CMOS, NMOS and TTL compatible  
• Push-pull outputs
