ST1G3234BJR Product Details


The ST1G3234 is a dual supply low voltage CMOS 1-Bit bus buffer level translator fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. Designed for use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/1.8V, 3.3V/2.5V, 1.8V/1.4V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation. This IC is intended for one-way asynchronous communication between data buses. The input and output power down protections disable the device when both power supply are down, so that the buses are effectively isolated. The input tolerant buffers allow to translate VCCB compatible signals and greater signals than VCCB up/down to VCCA. All inputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.


■ High speed: tPD = 4.4ns (Max.) at TA = 85°C VCCB = 1.65V; VCCA = 3.0V

■ Low power dissipation: ICCA = ICCB = 5µA(Max.) at TA = 85°C

■ Symmetrical output impedance: |IOHA| = IOLA = 10mA Min at VCCA = 2.75V; VCCB = 1.4V to 3.6V |IOHA| = IOLA = 6mA Min at VCCA = 2.3V; VCCB = 1.4V to 3.6V

■ Balanced propagation delays: tPLH ≅ tPHL

■ Power down protection on inputs and outputs

■ 26Ω series resistor on A-side outputs – Operating voltage range: VCCA(Opr) = 1.4V to 3.6V (1.2V data retent) VCCB(Opr) = 1.4V to 3.6V (1.2V data retent)
