INTRODUCTION

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
