General Description

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.

Overview

www.DataSheet4U.com ST1G3234 1-bit dual supply bus buffer level translator with A-side series.

Key Features

  • 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 reten.
