3.3V CMOS 18-BIT

IDT74LVCH16501A

REGISTERED BUS TRANSCEIVER

WITH 5V TOLERANT I/O

AND BUS-HOLD

FEATURES:

DESCRIPTION:

• Typical tSK(o) (Output Skew) < 250ps

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

This 18-bit registered transceiver is built using advanced dual metal

CMOS technology. This high-speed, low power 18-bit registered bus

transceivercombinesD-typelatchesandD-typeflip-flopstoallowdataflow

in transparent latched and clocked modes. Data flow in each direction is

controlled by output-enable (OEAB and OEBA), latch enable (LEAB and

LEBA) and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the

device operates in transparent mode when LEAB is high. When LEAB is

low,theAdataislatchedifCLKABisheldatahighorlowlogiclevel. IfLEAB

islow,theAbusdataisstoredinthelatch/flip-floponthelow-to-hightransition

of CLKAB. OEAB performs the output enable function on the B port. Data

flow from B port to A port is similar but requires using OEBA, LEBA and

CLKBA.Flow-throughorganizationofsignalpinssimplifieslayout.Allinputs

are designed with hysteresis for improved noise margin.

• 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 SSOP and TSSOP packages

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Reduced system switching noise

TheLVCH16501Ahasbeendesignedwitha ±24mAoutputdriver. This

driver is capable of driving a moderate to heavy load while maintaining

speedperformance.

The LVCH16501A has “bus-hold” which retains the inputs’ last state

whenevertheinputgoestoahighimpedance. Thispreventsfloatinginputs

and eliminates the need for pull-up/down resistors.

APPLICATIONS:

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
