INTRODUCTION

FEATURES

The UT54BS3245 provides eight channels of high-speed

CMOS compatible bus switching. The package is to provide a

standard ’245 device pin out. The low on-state resistance of

the switch allows connections to be made with minimal

propagation delay. The device is organized as one 8-channel

switch. When the output-enable (/EN) input is low, the switch

is on, and port A is connected to port B. When /EN is high, the

switch is open, and the high-impedance state exists between

the two ports.

□ 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 5 Ω 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:

APPLICATIONS INFORMATION

Memory Interface

Solution for multiple memory devices on a bus –

isolates heavy loading

- 20-lead flatpack

□ Standard Microelectronics Drawing (SMD)

- QML Q and V pending

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

Allows 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
