74ALVC16245; 74ALVCH16245

16-bit transceiver with direction pin; 3-state

Rev. 03 — 12 May 2004

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

■ Wide supply voltage range from 1.2 V to 3.6 V

■ Complies with JEDEC standard JESD8-B

■ CMOS low power consumption

■ MULTIBYTE ﬂow-through standard pin-out architecture

■ Low inductance multiple V_CCand 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 V_CC= 3.0 V.

17. Disclaimers

Short-form speciﬁcation — The data in a short-form speciﬁcation is

extracted from a full data sheet with the same type number and title. For

detailed information see the relevant data sheet or data handbook.

Life support — These products are not designed for use in life support

appliances, devices, or systems where malfunction of these products can

reasonably be expected to result in personal injury. Philips Semiconductors

at their own risk and agree to fully indemnify Philips Semiconductors for any

damages resulting from such application.

Limiting values deﬁnition — Limiting values given are in accordance with

the Absolute Maximum Rating System (IEC 60134). Stress above one or

more of the limiting values may cause permanent damage to the device.

These are stress ratings only and operation of the device at these or at any

other conditions above those given in the Characteristics sections of the

speciﬁcation is not implied. Exposure to limiting values for extended periods

may affect device reliability.

Right to make changes — Philips Semiconductors reserves the right to

make changes in the products - including circuits, standard cells, and/or

software - described or contained herein in order to improve design and/or

performance. When the product is in full production (status ‘Production’),

relevant changes will be communicated via a Customer Product/Process

Change Notiﬁcation (CPCN). Philips Semiconductors assumes no
