74LVC646A

Octal bus transceiver/register; 3-state

Rev. 5 — 28 March 2013

Product data sheet

1. General description

The 74LVC646A consists of non-inverting bus transceiver circuits with 3-state outputs,

D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly

from the internal registers. Data on the A or B bus is clocked in the internal registers, as

the appropriate clock (CPAB or CPBA) goes to a HIGH logic level. Output enable (OE)

and direction (DIR) inputs are provided to control the transceiver function. In the

transceiver mode, data present at the high-impedance port may be stored in either the A

or B register, or in both. With the select source inputs (SAB and SBA), stored and

real-time (transparent mode) data can be multiplexed. The direction (DIR) input

determines which bus receives data when OE is active (LOW). In the isolation mode (OE

= HIGH), A data may be stored in the B register and/or B data may be stored in the A

used to store and transmit data. Only one of the two buses A or B may be driven at a time.

Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be

applied to the outputs. These features allow the use of these devices as translators in

mixed 3.3 V and 5 V applications.

2. Features and benefits



5 V tolerant inputs/outputs for interfacing with 5 V logic

Supply voltage range from 1.2 V to 3.6 V

CMOS low-power consumption

Direct interface with TTL levels

8-bit octal transceiver with D-type latch

Back-to-back registers for storage

Separate controls for data flow in each direction

Supports partial power-down applications; inputs/outputs are high-impedance when

= 0 V



Complies with JEDEC standard:



JESD8-7A (1.65 V to 1.95 V)



JESD8-5A (2.3 V to 2.7 V)



JESD8-C/JESD36 (2.7 V to 3.6 V)



ESD protection:



HBM JESD22-A114F exceeds 2000 V



MM JESD22-A115-B exceeds 200 V



CDM JESD22-C101E exceeds 1000 V



Specified from

40 C

to +85

C

and

40 C

to +125

C.
