NTBA104
Dual supply translating transceiver; auto direction sensing;
3-state
Rev. 2 — 22 May 2012
Product data sheet
1. General description
The NTBA104 is a 4-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 4-bit input-output ports
(An and Bn), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). VCC(A)
can be supplied at any voltage between 1.2 V and 3.6 V and VCC(B) can be supplied at any
voltage between 1.65 V and 5.5 V, making the device suitable for translating between any
of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V).
Pins An and OE are referenced to VCC(A) and pins Bn are referenced to VCC(B). A HIGH
level at pin OE causes the outputs to assume a high-impedance OFF-state. This device is
fully specified for partial power-down applications using IOFF. The IOFF circuitry disables
the output, preventing the damaging backflow current through the device when it is
powered down.
2. Features and benefits
Wide supply voltage range:
VCC(A): 1.2 V to 3.6 V and VCC(B): 1.65 V to 5.5 V
IOFF circuitry provides partial Power-down mode operation
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JESD22-A114E Class 2 exceeds 2500 V for A port
HBM JESD22-A114E Class 3B exceeds 15000 V for B port
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1500 V
Latch-up performance exceeds 100 mA per JESD 78B Class II
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C

[1] The minimum input and minimum output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] VCCO is the supply voltage associated with the output.
[3] VCCO + 0.5 V should not exceed 6.5 V.
[4] For DHVQFN14 packages: above 60 C the value of Ptot derates linearly at 4.5 mW/K.
