MAX975
Description
The MAX975/MAX977 single/dual parators feature three different operating modes, and are optimized for +3V and +5V single-supply applications. The operating modes are as follows: high speed, high speed with auto-standby, and low power. Propagation delay is 28ns in high-speed mode, while supply current is only 250µA. Supply current is reduced to 3µA in low-power mode.
The auto-standby feature allows the parator to automatically change from low-power mode to highspeed mode upon receipt of an input signal. In the absence of an input signal, the parator reverts back to low-power mode after an adjustable timeout period. The timeout period for the MAX975 to enter standby is set by a single capacitor. The dual MAX977 features independently adjustable timeout periods for each parator using separate capacitors.
The MAX975/MAX977’s inputs have a mon-mode...
