3.3V CMOS 16-BIT
REGISTERED TRANSCEIVER
WITH 3-STATE OUTPUTS
AND 5 VOLT TOLERANT I/O
DESCRIPTION:
FEATURES:
This 16-bit registered transceiver is built using advanced dual metal
CMOStechnology. Thishigh-speed, lowpowerdeviceisorganizedastwo
independent 8-bit D-type registered transceivers with separate input and
output control for independent control of data flow in either direction. For
example, theA-to-BEnable(CEAB) mustbeLOW toenter datafromtheA
port.CLKABcontrolstheclockingfunction. WhenCLKABtogglesfromLOW-
to-HIGH, the data present on the A port will be clocked into the register.
OEABperformstheoutputenablefunctionontheBport. Dataflowfromthe
BporttoAportissimilarbutrequiresusingCEBA,CLKBA,andOEBAinputs.
Full16-bitoperationisachievedbytyingthecontrolpinsoftheindependent
transceiverstogether.
• Typical tSK(o) (Output Skew) < 250ps
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 3.3V ± 0.3V, Normal Range
• VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4µ W typ. static)
• All inputs, outputs, and I/O are 5V tolerant
• Supports hot insertion
• Available in TSSOP package
DRIVE FEATURES:
• Balanced Output Drivers: ±12mA
• Low switching noise
Allpinscanbedrivenfromeither3.3Vor5Vdevices. Thisfeatureallows
the use of this device as a translator in a mixed 3.3V/5V supply system.
The LVCR162952A has series resistors in the device output structure
which will significantly reduce line noise when used with light loads.This
driver has been developed to drive ±12mA at the designated threshold
levels.
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
