Product data sheet

1 General description

The 74ALVC16245; 74ALVCH16245 is a 16-bit transceiver featuring non-inverting

3-state bus compatible outputs in both send and receive directions.

The 74ALVC16245; 74ALVCH16245 features two output enable inputs (pins nOE) for

easy cascading and two send or receive inputs (pins nDIR) for direction control. Pins

nOE control the outputs so that the buses are effectively isolated. This device can be

used as two 8-bit transceivers or one 16-bit transceiver.

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 VCC and GND pins for minimize noise and ground bounce

• Direct interface with TTL levels

• All data inputs have bushold (74ALVCH16245 only)

• Output drive capability 50 Ω transmission lines at 85 °C

• Current drive ±24 mA at VCC = 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
