These bidirectional switches are latch-proof and feature break-before-make switching. Designed to block signals up to 30V peak-to-peak in the OFF state, the DG201A and DG202 offer the advantages of low on resistance (175), wide input signal range (15V) and provide both TTL and CMOS compatibility. o 0 C to +70 C 16 Lead SOIC (W) 16 Lead SOIC (W) DG202AK -55oC to +125oC DG202AK/883B -55oC to +125oC 16 Lead Ceramic DIP DG202BK -25oC to +85oC 16 Lead Ceramic DIP DG202CK 0oC to +70oC 16 Lead Ceramic DIP DG202CJ 0oC to +70oC 16 Lead Plastic DIP Pinout 16 Lead Ceramic DIP Functional Diagrams DG201A DG201A, DG202 (CDIP, PDIP, SOIC) TOP VIEW DG202 S1 IN1 1 D1 2 15 D2 S1 3 14 S2 GND 5 13 V+ (SUBSTRATE) 12 NC S4 6 11 S3 D4 7 IN4 8 V- 4 D1 16 IN2 IN1 10 D3 9 IN3 S1 IN1 D1 S2 IN2 S2 IN2 D2 D2 S3 IN3 S3 IN3 D3 D3 S4 S4 IN4 IN4 D4 D4 NOTES: 1.

Signals on VS, VD, or VIN exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current ratings. 2. Typical values are for design aid only, not guaranteed and not subject to production testing. 3. The algebraic convention whereby the most negative value is a minimum, and the most positive is a maximum, is used in this data sheet. 4. ID(ON) is leakage from driver into ON switch. 9-23 DG201A, DG202 Test Circuits LOGIC* 3V INPUT 50% tR < 20ns tF < 20ns SWITCH INPUT VO = VS LOGIC "0" = SWITCH ON RL RL + RDS(ON) SWITCH INPUT +15V V+ SWITCH OUTPUT VO S1 VS = +2V VS VO SWITCH 0V OUTPUT 0.9 0.9 VO LOGIC INPUT RL 1k IN1 tOFF tON GND V+ -15V 0V *Logic shown for DG201A, invert for DG202 CL 35pF (REPEAT TEST FOR IN2, IN3 AND IN4) FIGURE 1.
