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 VCC = 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 ANSI/ESDA/Jedec JS-002 exceeds 1000 V

• Specified from -40 °C to +85 °C and -40 °C to +125 °C
