ELECTRICAL CHARACTERISTICS

Note 3: SET POINT error

≡

– SET POINT

where VU = upper band limit and VL = lower band limit.

Note 4: Deadband error

≡ (VU – VL) – 2 • DELTA where VU = upper band

limit and VL = lower band limit.

VU + VL

Note 5: RIN is guaranteed by design and is not tested.

RIN = 1/(fS x 66pF).

Note 6: Average supply current = tD • IS(ON) • fS + (1 – tD • fS) lS(OFF).

Note 7: Response time is set by an internal oscillator and is independent

of overdrive voltage. tD = VP-P pulse width.

Note 8: Output also capable of meeting EIA/JEDEC standard B series

CMOS drive specifications.
