74ALVCH16646

16-bit bus transceiver/register; 3-state

Rev. 3 — 11 September 2018

Product data sheet

1. General description

The 74ALVCH16646 consists of 16 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 will be clocked in the internal registers, as the

appropriate clock (nCPAB or nCPBA) goes to a HIGH logic level. Output enable (nOE) and

direction (nDIR) 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.

The select source inputs (nSAB and nSBA) can multiplex stored and real-time (transparent mode)

data. The direction (nDIR) input determines which bus will receive data when nOE is active (LOW).

In the isolation mode (nOE = HIGH), ‘A’ data may be stored in the ‘B’ register and/or ‘B’ data may

be stored in the ‘A’ register.

When an output function is disabled, the input function is still enabled and may be used to store

and transmit data. Only one of the two buses, ‘A’ or ‘B’ may be driven at a time.

To ensure the high impedance state during power up or power down, nOE should be tied to V_CC

through a pullup resistor; the minimum value of the resistor is determined by the current-sinking/

current-sourcing capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

2. Features and benefits

[1] Please consult the most recently issued document before initiating or

completing a design.

Nexperia does not accept any liability related to any default, damage, costs

or problem which is based on any weakness or default in the customer’s

applications or products, or the application or use by customer’s third party

customer(s). Customer is responsible for doing all necessary testing for the

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

internal review and subject to formal approval, which may result in

modifications or additions. Nexperia does not give any representations or

warranties as to the accuracy or completeness of information included herein

and shall have no liability for the consequences of use of such information.

Short data sheet — A short data sheet is an extract from a full data sheet

with the same product type number(s) and title. A short data sheet is

intended for quick reference only and should not be relied upon to contain

detailed and full information. For detailed and full information see the relevant

full data sheet, which is available on request via the local Nexperia sales

automotive applications to automotive specifications and standards,

customer (a) shall use the product without Nexperia’s warranty of the

product for such automotive applications, use and specifications, and (b)

whenever customer uses the product for automotive applications beyond

Nexperia’s specifications such use shall be solely at customer’s own risk,

and (c) customer fully indemnifies Nexperia for any liability, damages or failed

product claims resulting from customer design and use of the product for

automotive applications beyond Nexperia’s standard warranty and Nexperia’s

product specifications.
