FEATURES
2.5V Operation
HCMOS Output
Low Power Consumption
Standby Function
Tape and Reel (2,000 pcs. STD)
1 Inclusive of 25C tolerance, operating temperature range, input voltage change, load change, ag-
ing, shock, and vibration. *Excludes Shock/Vibration
2 An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
Note: A 0.01F bypass capacitor should be placed between VDD (Pin 4) and GND (Pin 2) to
minimize power supply line noise.
Drawing is for reference to critical specifications defined by size measurements.
Certain non-critical visual attributes, such as side castellations, reference pin shape, etc. may
vary. All specifications subject to change without notice.
