74LCX32373

Preliminary 74LCX32373 Low Voltage 32-Bit Transparent Latch with 5V Tolerant Inputs and Outputs (Preliminary) January 2001 Revised August 2001 74LCX32373 Low Voltage 32-Bit Transparent Latch with 5V Tolerant Inputs and Outputs (Preliminary) General Description The LCX32373 contains thirty-two non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the outputs are in a high impedance state. The LCX32373 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX32373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Features I 5V tolerant inputs and outputs I 2.3V–3.6V VCC specifications provided I 5.4 ns tPD max (VCC = 3.3V), 20 µA ICC max I Power down high impedance inputs and outputs I Supports live insertion/withdrawal (Note 1) I ±24 mA output drive (VCC = 3.0V) I Uses patented noise/EMI reduction circuitry I Latch-up performance exceeds 500 mA I ESD performance: Human body model > 2000V Machine model > 200V I Packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary) Note 1: To ensure the high-impedance state during power up or down, OE s...
