DESCRIPTION/ORDERING INFORMATION

The SN74VMEH22501 8-bit universal bus transceiver has two integral 1-bit three-wire bus transceivers and is

designed for 3.3-V V_CCoperation with 5-V tolerant inputs. The UBT™ transceiver allows transparent, latched, and

flip-flop modes of data transfer, and the separate LVTTL input and outputs on the bus transceivers provide a

feedback path for control and diagnostics monitoring. This device provides a high-speed interface between cards

operating at LVTTL logic levels and VME64, VME64x, or VME320⁽¹⁾backplane topologies.

(1) VME320 is a patented backplane construction by Arizona Digital, Inc.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
