MAX3325 - 3V Dual RS-232 Transceiver

Datasheet Summary

Description

The MAX333A is a precision, quad, single-pole doublethrow (SPDT) analog switch.

The four independent switches operate with bipolar supplies ranging from ±4.5V to ±20V, or with a single-ended supply between +10V and +30V.

19-0189; Rev 1; 6/99 Precision, Quad, SPDT, CMOS Analog Switch _______________General Description The MAX333A is a precision, quad, single-pole doublethrow (SPDT) analog switch. The four independent switches operate with bipolar supplies ranging from ±4.5V to ±20V, or with a single-ended supply between +10V and +30V. The MAX333A offers low on resistance (less than 35Ω), guaranteed to match within 2Ω between channels and to remain flat over the analog signal range (∆3Ω max). It also offers break-before-make switching (10ns typical), with turn-off times less than 145ns and turn-on times less than 175ns. The MAX333A is ideal for portable operation since quiescent current runs less than 50µA with all inputs high or low.
