74LCX652
Low Voltage Transceiver/Register with 5V Tolerant
Inputs and Outputs
General Description
The LCX652 consists of bus transceiver circuits with D-
type flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the input bus or from
internal registers. Data on the A or B bus will be clocked
into the registers as the appropriate clock pin goes to the
HIGH logic level. Output Enable pins (OEAB, OEBA) are
provided to control the transceiver function.
The LCX652 is designed for low voltage (2.5V or 3.3V) VCC
applications with capability of interfacing to a 5V signal
environment.
The LCX652 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 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 mA output drive (VCC = 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.
