FEAtuRES

• Tight Stability

• 2.5V Operation

• HCMOS Output

• Standby Function

1

Inclusive of 25

ºC tolerance, operating temperature range, supply voltage change and aging.

2

An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.

*Note: A 0.01µF capacitor should be placed between V

dd (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.
