PI4ULS3V16 1.2V to 3.6V Universal Bi-directional Level Shifter with Automatic Direction Control Features Description • Designed for low voltage operation: 1.2V to 3.6V Pericom Semiconductor’s PI4ULS3V16 is a 16-bit (dual-octal) non-inverting bus transceiver with two separate supply rails. A port (VCCA) and B port (VCCB) are set to operate at 1.2V to 3.6V. This arrangement permits universal bidirectional translation of differential signal levels over the voltage ranges. • Universal bidirectional level shifting without direction control • Fast bus speeds up to 180 Mbps • Drive Capability 12mA PI4ULS3V16 is designed for asynchronous communication between data buses. Data is transmitted from the A bus to the B bus, or vice versa, without direction control. All AX, and BX are tri-stated when data is coming from both directions at the same time. The output-enable (OE) input is used to disable outputs so buses are isolated. • Independent transition of each bit • Each supply rail is configurable over supply range • ESD Protection exceeds JESD22 – 2000V Human Body Model (A114-B) – 200V Machine Model (A115-A) The control pins, xSEL, xOE, TEST_EN and OUT_SEL are supplied by VCCB. • Latch-up performance exceeds 100mA per JESD 78 • Industrial operation at –40°C to +85°C To ensure the high-impedance state during power-up or powerdown, the output-enable (OE) input should be tied to VCC through a pullup resistor. • Packaging (Pb-free & Green): – 56-pin plastic 240-mil TSSOP (A56) – 56-contact plastic 197-mil TQFN (ZF56) Applications • Voltage Translation Block Diagram 1SEL 2SEL OUT_SEL TEST_EN • Bus Relay Testing and Loading Logic TST 1OE 1A1 1B1 To Seven Other Channels 1SEL 2SEL OUT_SEL TEST_EN Testing and Loading Logic TST 2OE 2A1 2B1 To Seven Other Channels 07-0052 1 PS8775E 02/23/07 PI4ULS3V16 1.2V to 3.6V, Universal Bi-directional Level Shifter with Automatic Direction Control Maximum Ratings (Absolute maximum ratings over operating free-air temperature range, unless otherwise noted) Supply voltage range: VCCA .................... –0.5V to 4.6V VCCB .................... –0.5V to 4.6V Input voltage range, VI(1) Control Inputs ...... –0.5V to 4.6V Voltage Range applied to any I/O pins in the high-impedance or Power-Off state, VIO (1) : A Port ....................... –0.5V to 4.6V B Port ................... –0.5V to 4.6V Voltage Range applied to any I/O pins in the High or Low state VIO (1, 2): A Port ......... –0.5V to VCCA +0.5V B Port ....... –0.5V to VCCB +0.5V Input clamp current, IIK (VI <0) ................................... –50mA Output clamp current, IOK (VO <0).............................. –50mA Continuous output current, IO ....................................... ±20mA Continuous current through VCCA, VCCB or GND ..... ±100mA Package thermal impedance, 0JA(3): A package............................. 82°C/W ZF package........................... 33°C/W Storage temperature range, TSTG .................... –65°C to 150°C Note: 1. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. This value is limited to 3.6V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. 4. Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
