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

Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. Functional
operation should be restricted to recommended operating conditions. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability and performance.
2. All voltages referenced to VSS

Notes:
* For devices procured with a total ionizing dose tolerance guarantee, the post-irradiation
performance is guaranteed at 25°C per MIL-STD-883 Method 1019, Condition A up to the
maximum TID level procured.
1. The propagation delay through the channel is based upon the RC time constant of the channel
resistance and switch ON capacitance, 11 and 17pF.
