XD7555
Low power consumption, universal timer
Leaky pulse detector
Pulse position modulation
Precise timing
Pulse width modulation
Sequential timing
The XD7555 is a CMOS RC timer that offers a significant performance improvement over the standard 555NE and 355 timers, while being a direct replacement for these devices in most applications. Improved parameters include low supply current, wide operating supply voltage range, low threshold, trigger and reset currents, no overload of supply current during output conversion, higher frequency performance, and no need to decouple control voltage for stable operation. Specifically, the XD7555 is a stable controller capable of producing precise time delays or frequencies.
● Very low input current: 20pA
● High speed operation: 1MHz
● Guaranteed supply voltage range: 2V to 18V
● Temperature stability: 0.005%/°C at +25°C
● Normal reset function - no power short circuit during output conversion
● Can be used with a higher impedance timing element than the regular 555 to obtain a longer RC time constant
● From microseconds to hours of timing
● Operating in unstable and single stable modes
● Adjustable duty cycle
● High output source/sink drivers can drive TTL/CMOS
● The output has very low offset, high and low
