74ALVC16245; 74ALVCH16245

16-bit transceiver with direction pin; 3-state

Rev. 6 — 5 August 2021

Product data sheet

1. General description

The 74ALVC16245; 74ALVCH16245 is a 16-bit transceiver with 3-state outputs. The device can be

used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables

(1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for

direction control. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. This

device is fully specified for partial power down applications using I_OFF. The I_OFFcircuitry disables

the output, preventing the potentially damaging backflow current through the device when it is

powered down.

The 74ALVCH16245 has an active bushold circuitry which is provided to hold unused or floating

data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down

resistors.

2. Features and benefits

•

Wide supply voltage range from 1.2 V to 3.6 V

•

CMOS low power consumption

MULTIBYTE flow-through standard pin-out architecture

Low inductance multiple V_CCand GND pins for minimize noise and ground bounce

Overvoltage tolerant inputs to 5.5 V

Direct interface with TTL levels

I_OFFcircuitry provides partial Power-down mode operation

All data inputs have bushold (74ALVCH16245 only)

Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Output drive capability 50 Ω transmission lines at 85 °C

Current drive ±24 mA at V_CC= 3.0 V.

Complies with JEDEC standards:

•

JESD8-5 (2.3 V to 2.7 V)

JESD8B/JESD36 (2.7 V to 3.6 V)

•

ESD protection:

•

HBM ANSI/ESDA/JEDEC JS-001 exceeds 2000 V

CDM JESD22-C101E exceeds 1000 V
