Q = 7pC typ * High Speed. tON = 8ns typ * Very Good Off-Isolation: -55dB @ 10 MHz * Wide -3dB Bandwidth: 230 MHz * High-Current Channel Capability: >100mA * TTL/CMOS Logic Compatible * Low Power Consumption (0.5W typ) * Pin-compatible with DG40X, MAX38X Description The PI5A381/383/385A are dual monolithic analog switches designed for single-supply operation. These high-precision devices are ideal for low-distortion audio, video signal switching and routing. The PI5A381 is a dual single-pole single-throw (SPST), normally open (NO) switch. The PI5A383 is a dual single-pole double-throw (SPDT) switch. The PI5A385 is a dual doublepole single-throw (DPST), normally open (NO) function. Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails. The PI5A381/383/385 are fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <10 on-resistance. Onresistance matching between channels is within 2. Onresistance flatness is less than 4 over the specified range. The PI5A38X family guarantees fast switching speeds (tON < 15ns). These products are available in the 16-pin narrow-body SOIC, QSOP, and PDIP packages for operation over the industrial (-40oC to +85 oC) temperature range. * * * * * * Applications Audio, Video Switching and Routing Battery-Powered Communication Systems Computer Peripherals Telecommunications Portable Instrumentation Replaces Mechanical Relays Functional Diagram, Pin Configurations and Truth Tables COM1 NIC COM3 NC3 NC4 COM4 NIC COM2 1 2 3 4 5 6 7 8 PI5A383A 16 NO1 15 IN1 14 NIC 13 GND 12 NIC 11 VCC 10 IN2 9 NO2 Switches shown for Logic "0" input NC = Normally Closed, NO = Normally Open, NIC = Not internally Connected PI5A381A Logic 0 1 Switch O FF ON Logic 0 1 PI5A383A SW1, SW2 O FF ON SW3, SW4 ON O FF PI5A385A Logic 0 1 Switch O FF ON 32 PS7062D 07/14/98 21098765432121098765432109876543210987654321210987654321098765432109876543212109876543210987654321098765432121098765432109876543210987654321 21098765432121098765432109876543210987654321210987654321098765432109876543212109876543210987654321098765432121098765432109876543210987654321 21098765432121098765432109876543210987654321210987654321098765432109876543212109876543210987654321098765432121098765432109876543210987654321 PI5A381A PI5A383A PI5A385A Absolute Maximum Ratings Voltages Referenced to GND VCC ................................................................................................................................... -0.5V to +7V .......................................................................................
