74LCX16646
Low Voltage 16-Bit Transceiver/Register
with 5V Tolerant Inputs and Outputs
General Description
The LCX16646 contains sixteen non-inverting bidirectional
registered bus transceivers with 3-STATE outputs, provid-
ing multiplexed transmission of data directly from the input
bus or from the internal storage registers. Each byte has
separate control inputs which can be shorted together for
full 16-bit operation.The DIR inputs determine the direction
of data flow through the device. The CPAB and CPBA
inputs load data into the registers on the LOW-to-HIGH
transition (see Functional Description).
The LCX16646 is designed for low voltage (2.5V or 3.3V)
VCC applications with capability of interfacing to a 5V signal
environment.
The LCX16646 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 5.2 ns tPD max (VCC = 3.3V), 20 A ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s
±24 mA Output Drive (V
CC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human Body Model
> 2000V
Machine Model
> 200V
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
