B162835
Registered 18-Bit Bus Driver
IMI CONFIDENTIAL
Product Description (Cont.)
If the function of the register is not needed then, LE may
be asserted high and the device becomes transparent,
therefore, data applied at IN(1:18) will propagate to
OUT(1:18) regardless of the clock condition. This
device features an OE signal for tri-stating all outputs.
Advanced Information
18-bit universal bus driver
Single stage register for data synchronization
Fast Input to Output Propagation delay (2.9nS,
Typ.)
Supports high frequency clocking up to 150MHz
Integrated Damping resistor on each output.
2KV ESD protection
Operates from 2.3V to 3.6V
Available in 56 pin SSOP, TSSOP, and TVSOP
packages
Pin Configuration
Product Description
The B162835 is an universal bus driver with a single
stage register for re-synchronizing the data. While LE is
asserted Low, the rising edge of the clock, will transmit
the data from the inputs at IN(1:18) to the outputs at
OUT(1:18).
