HEF4104BT-Q100J

Translators, Level Shifters Overview

The HEF4104BT-Q100J is a quad low-to-high voltage translator with complementary 3-state outputs, qualified to AEC-Q100 Grade 3. It operates within a supply voltage range of 3.0 V to 15.0 V and supports an ambient temperature range from -40 °C to +85 °C. The device features inputs with clamp diodes for interfacing voltages exceeding VDD(A). Propagation delays vary by supply voltage; at 5 V, typical delay is 170 ns, while at 15 V, it reduces to 65 ns (tPHL) and 70 ns (tPLH). Dynamic power dissipation formulas are provided for 5 V, 10 V, and 15 V operations.

Translators, Level Shifters FAQ

How does the OE input affect the register state?

A LOW on the output enable (OE) input causes the outputs to assume a high-impedance OFF-state. This action does not affect the internal state of the data being translated.

What is the purpose of the input clamp diodes?

The inputs include clamp diodes, which enable the use of current limiting resistors to interface inputs to voltages in excess of VDD(A).
