The low ON Resistance (RON) of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. STMAV335 is designed for very low cross-talk, low bit-to-bit skew, high channel-to-channel noise isolation and low I/O capacitance. The switch offers very little or practically no attenuation of the high-speed signals at the outputs, thus preserving the signal integrity to pass stringent requirements. Moreover the device reduces the overall BOM costs by eliminating the need for more costly multi input-output controllers. ■ DVD Players Order Codes Part Number STMAV335 Temperature Range –40°C to +85°C Package TSSOP16 Comments STMAV335TTR January 2006 Rev. 1 1/21 www.st.com 21 Contents STMAV335 1 Summary Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.1 Functional Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2 Pin Configuration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 3 Application Diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 3.1 Power Supply Sequencing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 ct(s) 4 Maximum Ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 rodu 5 Electrical Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 te P 6 AC Loading and Diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 sole 7 Test Circuits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 - Ob 8 Package Mechanical Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 Obsolete Product(s) 9 Revision History . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 2/21 STMAV335 1 Summary Description 1 Summary Description 1.1 Functional Description The STMAV335 is a high bandwidth analog video switch. Its low ON-resistance and low I/O capacitance result in a very small propagation delay. The combination of SEL1 and SEL2 is used to either disable or enable the desired video channel. Refer to the truth table for the selection of the appropriate channels. Figure 1.
