74AVC20T245
20-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Rev. 7 — 8 March 2012
Product data sheet
1. General description
The 74AVC20T245 is a 20-bit, dual supply transceiver that enables bi-directional voltage
level translation. The device can be used as two 10-bit transceivers or as a single 20-bit
transceiver. It features four 10-bit input-output ports (1An, 1Bn and 2An, 2Bn), two output
enable inputs (nOE), two direction inputs (nDIR) and dual supplies (VCC(A) and VCC(B)).
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 bi-directional voltage level translation between any of the
low voltage nodes: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. The 1An and 2An ports, nOE
and nDIR are referenced to VCC(A), the 1Bn and 2Bn ports are referenced to VCC(B). A
HIGH on a 1DIR allows transmission from 1An to 1Bn and a LOW on 1DIR allows
transmission from 1Bn to 1An. 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, all output ports will assume a high impedance OFF-state.
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:

JESD8-7 (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-C101C exceeds 1000 V

CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + (CL VCC2 fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
(CL VCC2 fo) = sum of the outputs.
[2]
fi = 10 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL = .

with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.
