Standard Products UT54BS16245 16bit Bus Switch Preliminary Datasheet February 2015 www.aeroflex.com/busswitch FEATURES INTRODUCTION □ Provides cold-sparing capability without the need for actual cold-sparing multiplexer inputs □ Bidirectional operation □ 3.3V operating lower supply with typical 11Ω switch connection between ports □ 5V operating lower supply with typical 5Ω switch connection between ports □ Isolates non cold-spared devices from an active bus □ Ultra low power CMOS technology □ ESD rating HBM: 2000V, Class 2 □ Operational environment: - Total dose: 300 krad(Si) - Latchup immune (LET <= 100 MeV-cm2/mg) □ Packaging: - 48-lead flatpack □ Standard Microcircuit Drawing (SMD) - QML Q and V pending The UT54BS16245 provides 16 bits of high-speed CMOS-compatible bus switching in a standard ’16245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 8-bit low-impedance switches with separate output-enable (/EN) inputs. When OE is low, the switch is on, and data can flow from the A port to the B port, or vice versa. When /EN is high, the switch is open, and the high-impedance state exists between the two ports. APPLICATIONS INFORMATION Memory Interface - Solution for multiple memory devices on a bus Bus Isolation - Ability to electrically isolate a device, or banks of devices, from memory bus or ADC output when not needed - Enables bank switching for redundancy or device failure - Provides cold-sparing capability without the need for actual cold-sparing buffers Redundancy - llows multiple non cold-spare devices to be present on a bus Supports Analog Applications - In voltage range: 3.0 to 3.6V or 4.5 to 5.5V - Signal isolation: -60dB - Bandwidth (3dB): 500 MHz 1A1 1B1 2A1 2B1 1A8 1B8 2A8 2B8 /EN1 /EN2 Figure 1.
