MICOM DATA MM74HC4051 8-CHANNEL ANALOG MULTIPLEXER GENERAL DESCRIPTION The MM74HC4051, MM74HC4052 and MM74HC4053 Multiplexers are digitally controlled analog switches implemented in advanced silicon-gate CMOS technology. These switches have low “on” resistance and low “off” leakages. They are bidirectional switches, thus any analog input may be used as an output and vice-versa. - Page 3 CONNECTION DIAGRAMS PHYSICAL DIMENSIONS (Pin Assignments for DIP, SOIC, SOP and TSSO) inches (millimeters) unless otherwise noted Top View TRUTH TABLES Input “ON” Channel None LOGIC DIAGRAMS...

- Page 11 CLOCK SIGNALS Type Function Test Mode Select (JTAG). Used to control the test state machine. TMS has a 20kΩ internal pull-up resistor. The ADSP-21065L can use an external clock or a crystal. See CLKIN pin description. You can configure the ADSP-21065L to use its internal clock generator by connecting the necessary components to CLKIN and Test Data Input (JTAG).
