• Manufacturer Part Number: MAX14760
• Description: The MAX14760/MAX14762/MAX14764 analog switches are capable of passing bipolar signals that are beyond their supply rails
• Manufacturer: Maxim

The MAX14760/MAX14762/MAX14764 analog switches
are capable of handling signals above and below their
rails. These devices operate from a single +3.0V to +5.5V
supply and support signals in the -25V to +25V range.
The devices switch signals in the range from -25V to
+25V that are above and below their rails. The on-resis-
tance for these devices exhibits a high degree of flatness
(58mI) over the whole input voltage range of -25V to
+25V. The analog switches allow bidirectional current
flow, so A, A1, A2, B, B1, B2, and COM, can be used as
either inputs or outputs.
Bias-stabilizing capacitors are required on the V
pins. 1FF ceramic capacitors are suggested for effective
operation. V
for other circuitry.
