| 19-0309; Rev 1; 6/99 TTL Compatible CMOS Analog Switches General Description Maxim's DG300-DG303 and DG300A-DG303A CMOS dual and quad analog switches combine low power operation with fast switching times and superior DC and AC switch characteristics. On-resistance is less than 50 and is essentially constant over the analog signal range. Device specifications are ideal for batterypowered circuitry. These switches are available in a variety of formats as outlined in the Pin Configurations section. The switch control logic inputs are fully TTL and CMOS compatible. Also featured are "break-before-make" switching and low charge injection. Maxim's DG300-DG303 and DG300A-DG303A families are electrically compatible and pin compatible with the original manufacturer's devices. All devices operate with power supplies ranging from 5V to 18V. Single-supply operation is implemented by connecting V- to GND. o Monolithic Low-Power CMOS o Latchup Proof Construction o Fully Compatible 2nd Source o Low On-Resistance, <50 o Fast Switching Time o V+ to V- Analog Signal Range o Single-Supply Capability Features DG300(A)/DG301(A)/DG302(A)/DG303(A) Ordering Information PART DG300C/D DG300CJ DG300CWE DG300CK DG300BWE DG300BK DG300BA DG300AK DG300AA TEMP RANGE 0C to +70C 0C to +70C 0C to +70C 0C to +70C -25C to +85C -25C to +85C -25C to +85C -55C to +125C -55C to +125C PIN-PACKAGE Dice 14 Lead Plastic DIP 16 Lead Wide SO 14 Lead CERDIP 16 Lead Wide SO 14 Lead CERDIP 10 Lead Metal Can 14 Lead CERDIP 10 Lead Metal Can Applications Portable Instruments Low-Power Sample/Holds Power-Supply Switching Programmable Gain Ampliffiers SPDT and DPDT Functions Process Control and Telemetry Ordering Information continued at end of data sheet.

They can also be used with single-ended power supplies ranging from +10V to +30V where the Vterminal is connected to ground. In either case, analog signals ranging from V+ to V- can be switched. The on-resistance variation with analog signal and supply voltage is shown in the Typical Operating Characteristics. The temperature coefficient of RON is typically 0.5%/C. Typical on-resistance matching from channel to channel is 10%. In addition, Table 1 outlines some typical parameters for single-supply operation. Table 2.
