MILPITAS, CA--(Marketwire - May 26, 2009) - [ Intersil ] Corporation (NASDAQ: [ ISIL ]), a world leader in the design and manufacture of high-performance analog and mixed signal semiconductors, today introduced a new series of voltage logic level translators (VLTs) featuring industry-leading ESD protection and 100 Megabit/second data rates for translating fast data streams.

The new [ ISL3034E ] and [ ISL3035E ] are six-channel, auto-direction sensing, bidirectional voltage level translators that ease the interface between mixed supply voltage peripherals and controllers. They are ideal for 3.3V SD, mini SD, memory stick and multimedia card applications that require I/O signal translation to the industry's latest low-voltage system controllers. The ISL3036E delivers the same industry-leading performance in a four-channel configuration.

With IEC61000-4-2 +/-15kV Air Gap, +/-9kV contact, and +/-15kV HBM protection on all input, output and I/O lines, these new translators provide the industry's best ESD protection. This is especially important in SD memory card applications, where the translator resides at the edge of the connector and can be vulnerable to ESD events.

The ISL3034E/35E/36E series features auto-direction sensing, eliminating the need for direction control logic pins and associated software control, making them excellent design choices for memory-card level translation or for general-purpose applications. In addition the auto-direction sensing function allows bit-by-bit determination of signal flow.

The new voltage level translator (VLTs) operate with VCC (SD card supply) voltages from +2.2V to +3.6V and VL voltages from +1.35V to +3.2V, enabling data transfer between low-voltage MCUs or ASICs and higher voltage components, such as SD cards. These power supply ranges allow level shifting between 1.5V, 1.8V, and 2.5V powered devices on the VL (system controller supply side) and 2.5V and 3.3V devices on the VCC side.

Each I/O channel is pulled up to VCC or VL by an internal 30µA current source, allowing the VLTs to be driven by either push-pull or open-drain drivers.

The ISL3034E and [ ISL3036E ] also have an enable (EN) input that places the IC into a low-power shutdown mode when the input is driven low. All versions feature an automatic shutdown mode that places the part in the same low power state when VCC is less than VL. The ISL3035E features a clock return output that returns the same signal applied to the clock VL input, but with a delay that better mimics the timing of data read back from a memory card.

Packaging, Pricing and Availability

Each is now available in tiny 2.6 mm x 1.8 mm 16 leadless µTQFN packages, which are superior to chip scale packages because they do not crack or break under stress, and have improved pin access for easier debug and rework access.

Pricing starts at $0.79 each in 1,000-piece quantities for the ISL3034E and ISL3035E; the ISL3036E is available at $0.71 each in 1,000-unit quantities.
