ADG526A APPLICATIONS ADG527A Data acquisition systems Communication systems Automatic test equipment Microprocessor controlled systems S1A DA S8A S1B DB S8B The ADG526A and ADG527A are CMOS monolithic analog multiplexers with 16 single channels and dual 8 channels, respectively. On-chip latches facilitate microprocessor interfacing. WR The ADG526A switches one of 16 inputs to a common output, depending on the state of four binary addresses and an enable input. The ADG527A switches one of eight differential inputs to a common differential output, depending on the state of three binary addresses and an enable input. Both devices have TTL and 5 V CMOS logic-compatible digital inputs. The ADG526A and ADG527A are designed on an enhanced LC2MOS process that gives an increased signal capability of VSS to VDD and enables operation over a wide range of supply voltages. The devices can comfortably operate anywhere in the 10.8 V to 16.5 V single- or dual-supply range. These multiplexers also feature high switching speeds and low RON. DECODER/ LATCHES A0 A1 A2 EN RS 01532-002 GENERAL DESCRIPTION Figure 2. ADG527A PRODUCT HIGHLIGHTS 1. Single- or Dual-Supply Specifications with a Wide Tolerance. The devices are specified in the 10.8 V to 16.5 V range for both single and dual supplies. 2. Easily Interfaced. The ADG526A and ADG527A can be easily interfaced with microprocessors. The WR signal latches the state of the address control lines and the enable line. The RS signal clears both the address and enable data in the latches, resulting in no output (all switches off). RS can be tied to the microprocessor reset pin. 3. Extended Signal Range. The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range from VSS to VDD. 4. Break-Before-Make Switching. Switches are guaranteed break-before-make so that input signals are protected against momentary shorting. 5. Low Leakage. Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits. Rev. C Information furnished by Analog Devices is believed to be accurate and reliable.

C | Page 12 of 20 ADG526A/ADG527A TIMING Figure 13 shows the timing sequence for latching the switch address and enable inputs. The latches are level sensitive; therefore, while WR is held low, the latches are transparent and the switches respond to the address and enable inputs. This input data is latched on the rising edge of WR. Figure 14 shows the reset pulse width, tRS, and reset turn-off time, tOFF (RS). Note that all digital input signal rise and fall times are measured from 10% to 90% of 3 V, tR = tF = 20 ns. 3V 3V 0V tW tS 3V EN, A0, A1, A2, (A3) 0V 1.5V tRS tOFF (RS) tH 2.0V 0.8V VO SWITCH OUTPUT 0V Figure 13.
