DG3157 Vishay Siliconix High-Speed, Low RON, SPDT Analog Switch (2:1 Multiplexer/Demultiplexer Bus Switch) DESCRIPTION FEATURES The DG3157 is a high-speed single-pole double-throw, low power, TTL-Compatible bus switch. Using sub-micro CMOS technology, the DG3157 achieves low on-resistance and negligible propagation delay. • Halogen-free According to IEC 61249-2-21 The DG3157 can handle both analog and digital signals and permits signals with amplitudes of up to VCC to be transmitted in either direction. • 1.65 V to 5.5 V VCC operation • Direct cross to industry standard SN74LVC1G3157, NC7SB3157, NLASB3175, Pl5A3157, and STG3157 • SC-70 6-lead package • 5 Ω connection between ports • Minimal propagation delay • Break-before-make switching When the Select pin is low, B0 is connected to the output A pin. When the Select pin is high, B1 is connected to the output A pin. The path that is open will have a highimpedance state with respect to the output. Make-beforebreak is guaranteed. An eptiaxial layer prevents latch-up. • Zero bounce in flow-through mode FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION SC-70 6-Pin B1 1 6 S GND 2 5 V+ B0 3 4 A Top View Device Marking: G1 TRUTH TABLE ORDERING INFORMATION Logic Input (S) Function 0 B0 Connected to A 1 Document Number: 72648 S09-0294-Rev.

Typical values are for design aid only, not guaranteed nor subject to production testing. d. Guarantee by design, nor subjected to production test. e. VIN = input voltage to perform proper function. f. Guaranteed by design and not production tested. The bus switch propagation delay is a function of the RC time constant contributed by the on-resistance and the specified load capacitance with an ideal voltage source (zero output impedance) driving the switch. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Document Number: 72648 S09-0294-Rev.
