74AVCH16T245  
16-bit dual supply translating transceiver with configurable  
voltage translation; 3-state  
Rev. 5 — 1 March 2012  
Product data sheet  
1. General description  
The 74AVCH16T245 is a 16-bit transceiver with bidirectional level voltage translation and  
3-state outputs.The device can be used as two 8-bit transceivers or as a 16-bit  
transceiver. It has dual supplies (VCC(A) and VCC(B)) for voltage translation and four 8-bit  
input-output ports (nAn, nBn) each with its own output enable (nOE) and send/receive  
(nDIR) input for direction control. VCC(A) and VCC(B) can be independently supplied at any  
voltage between 0.8 V and 3.6 V making the device suitable for low voltage translation  
between any of the following voltages: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. A HIGH  
on nDIR selects transmission from nAn to nBn while a LOW on nDIR selects transmission  
from nBn to nAn. A HIGH on nOE causes the outputs to assume a high-impedance  
OFF-state  
The device is fully specified for partial power-down applications using IOFF. The IOFF  
circuitry disables the output, preventing any damaging backflow current through the  
device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at  
GND level, both A and B outputs are in the high-impedance OFF-state. The bus-hold  
circuitry on the powered-up side always stays active.  
The 74AVCH16T245 has active bus hold 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 and benefits  
Wide supply voltage range:  
VCC(A): 0.8 V to 3.6 V  
VCC(B): 0.8 V to 3.6 V  
Complies with JEDEC standards:  
JESD8-12 (0.8 V to 1.3 V)  
JESD8-11 (0.9 V to 1.65 V)  
JESD8-7 (1.2 V to 1.95 V)  
JESD8-5 (1.8 V to 2.7 V)  
JESD8-B (2.7 V to 3.6 V)  
ESD protection:  
HBM JESD22-A114F Class 3B exceeds 8000 V  
MM JESD22-A115-A exceeds 200 V  
CDM JESD22-C101D exceeds 1000 V  
Maximum data rates:  
380 Mbit/s (1.8 V to 3.3 V translation)
