the 1.8V to 3.6V VCC operating range.
• Broad operating range: VCC = 1.8V –3.6V
Pericom’s PI74ST series of products are produced using the
Company’s advanced submicron technology.
• Power down high-impedance inputs/outputs
• High output drive: ±24mA at 3V VCC

Note:
Absolute maximum ratings are DC values beyond which
the device may be damaged or have its useful life
impaired. The datasheet specifications should be met,
without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/
input loading variables. Pericom does not recommend
operation outside datasheet specifications.

Notes:
3. CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption
(ICCD) at no output loading and operating at 50% duty cycle (see Figure 2). CPD is related to ICCD dynamic operating current by
the expression: ICCD = (CPD)(VCC)(fIN) + (ICC static).
