Single/Dual, Ultra-Fast, Low-Power Precision TTL Comparators MAX912/MAX913 General Description Features
The MAX913 single and MAX912 dual, high-speed, ♦
Ultra Fast (10ns)
low-power comparators have differential inputs and complementary TTL outputs. Fast propagation delay ♦
Single +5V or Dual ±5V Supply Operation
(10ns, typ), extremely low supply current, and a wide ♦
Input Range Extends Below Negative Supply
common-mode input range that includes the negative rail make the MAX912/MAX913 ideal for low-power, ♦
Low Power: 6mA (+5V) Per Comparator
high-speed, single +5V (or ±5V) applications such as ♦
No Minimum Input Signal Slew-Rate Requirement
V/F converters or switching regulators. ♦
No Power-Supply Current Spiking
The MAX912/MAX913 outputs remain stable through the linear region. This feature eliminates output instabili- ♦

Inputs Can Exceed Either Supply
with a slow-moving input signal. The MAX912/MAX913 can be powered from a single ♦
Low Offset Voltage: 0.8mV
+5V supply or a ±5V split supply. The MAX913 is an ♦
