PI4ULS3V08MZLE

Translators, Level Shifters Overview

The PI4ULS3V08MZLE is an 8-bit non-inverting bus transceiver featuring universal bidirectional level shifting with automatic direction control. It operates on two separate supply rails, VCCA and VCCB, both configurable within a 1.2V to 3.6V range. The device supports fast bus speeds up to 90 Mbps for push-pull applications and provides a drive capability of 12mA. It allows independent translation of each bit without requiring explicit direction control signals. The component includes ESD protection exceeding JESD22 standards and latch-up performance exceeding 100mA per JESD 78.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix ZLE confirms lead-free and green material composition as documented in the manufacturer's ordering information. Ensure the package code matches the 32-contact TQFN 3x6 specification. Confirm that the device meets industrial temperature operation requirements ranging from -40° C to +85° C. Cross-reference the part number against the latest datasheet revision to ensure compatibility with current design specifications.

Translators, Level Shifters Selection Notes

Select this component when asynchronous communication between data buses requires voltage translation between 1.2V and 3.6V domains. It is suitable for applications needing independent bit-level translation without direction control logic. Consider the 32-pin TQFN package for space-constrained designs. Verify that the required bus speed does not exceed the maximum frequency limits defined by the load capacitance and supply voltage conditions.

Translators, Level Shifters FAQ

How is the high impedance state ensured during power-up or power-down?

The output-enable (OEx) input should be tied to VCC through a pull-up resistor to ensure the high impedance state during power-up or power-down.

What is the function of the TEST_EN and OUT_SEL pins?

These control pins, supplied by VCCB, enable test modes and select output impedance levels (low or high) for normal operation or testing.
