74LVC16245A; 74LVCH16245A

16-bit bus transceiver with direction pin; 5 V tolerant; 3-state

Rev. 12 — 13 February 2012

Product data sheet

1. General description

The 74LVC16245A; 74LVCH16245A are 16-bit transceivers featuring non-inverting

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

two output enable (nOE) inputs for easy cascading and two send/receive (nDIR) inputs for

direction control. nOE controls the outputs so that the buses are effectively isolated. This

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

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 in mixed

3.3 V and 5 V applications.

The 74LVCH16245A bus hold on data inputs eliminates the need for external pull-up

resistors to hold unused inputs.

2. Features and benefits

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

 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 power and ground pins for minimum noise and ground

bounce

 Direct interface with TTL levels

 High-impedance when V_CC= 0 V

 All data inputs have bus hold (74LVCH16245A only)

 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
