74LVC16245A-Q100;
74LVCH16245A-Q100
16-bit bus transceiver with direction pin; 5 V tolerant; 3-state
Rev. 1 — 20 November 2012
Product data sheet
1. General description
The 74LVC16245A-Q100; 74LVCH16245A-Q100 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-Q100 bus hold on data inputs eliminates the need for external
pull-up resistors to hold unused inputs.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits
Automotive product qualification in accordance with AEC-Q100 (Grade 1)
