ST4G3235 4-bit dual supply bus buffer level translator with a side series resistor Features High speed: t = 4.3ns (Max.) at T = 85C PD A V = 1.65V V = 3.0V CCB CCA Low power dissipation: I = I = 5A(Max.) at T =85C CCA CCB A Symmetrical output impedance: I = I = 10mA Min at OHA OLA V = 2.75V V = 1.4V to 3.6V CCA CCB Flip-Chip11 I = I = 4mA Min at OHB OLB V = 1.65V V = 1.4 to 3.6V) CCB CCA Balanced propagation delays: Description t t PLH PHL The ST4G3235 is a dual supply low voltage Power down protection on inputs and outputs CMOS 4-bit bus buffer level translator fabricated 26 series resistor on a side outputs with sub-micron silicon gate and five-layer metal 2 Operating voltage range: wiring C MOS technology. Designed for use as an V (Opr) = 1.4V to 3.6V interface between a 3.3V bus and a 2.5V or 1.8V CCA V (Opr) = 1.4V to 3.6V bus in a mixed 3.3V/1.8V, 3.3V/2.5V, 1.8V/1.4V CCB and 2.5V/1.8V supply systems, it achieves high Max data rates: speed operation while maintaining the CMOS low 380Mbps (1.8V to 3.3V translation) power dissipation. 260Mbps (<1.8V to 3.3V translation) 260Mbps (translate to 2.5V) This IC is intended for one-way asynchronous 210Mbps (translate to 1.5V) communication between data buses. The input and output power down protections disable the Latch-up performance exceeds 500mA device when both power supply are down, so that (JESD 17) the buses are effectively isolated. ESD performance: HBM > 2000V (MIL STD 883 method 3015) The input tolerant buffers allow to translate V CCB MM > 200V compatible signals and greater signals than V CCB up/down to V and viceversa. CCA R HS compliant for Flip-Chip package O All inputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage. Table 1.
