74LVC16245A; 74LVCH16245A  
16-bit bus transceiver with direction pin; 5 V tolerant; 3-state  
Rev. 14 — 24 September 2021  
Product data sheet  
1. General description  
The 74LVC16245A; 74LVCH16245A is a 16-bit transceiver with 3-state outputs. The device can be  
used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables  
(1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for  
direction control. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.  
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices  
as translators in mixed 3.3 V and 5 V environments.  
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.  
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry  
disables the output, preventing the potentially damaging backflow current through the device when  
it is powered down.  
The 74LVCH16245A bus hold on data inputs eliminates the need for external pull-up resistors to  
hold unused inputs.  
2. Features and benefits  
Overvoltage tolerant inputs to 5.5 V  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low power dissipation  
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  
IOFF circuitry provides partial Power-down mode operation  
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
