Revised August 2001 74VCX32374 Low Voltage 32-Bit D-Type Flip-Flops with 3.6V Tolerant Inputs and Outputs General Description Features The VCX32374 contains thirty-two non-inverting D-type flip-flops with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. A buffered clock (CP) and output enable (OE) are common to each byte and can be shorted together for full 32-bit operation. ■ 1.65V–3.6V VCC supply operation The 74VCX32374 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX32374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. ■ 3.6V tolerant inputs and outputs ■ tPD 3.0 ns max for 3.0V to 3.6V VCC 3.9 ns max for 2.3V to 2.7V VCC 7.8 ns max for 1.65V to 1.95V VCC ■ Power-off high impedance inputs and outputs ■ Supports live insertion and withdrawal (Note 1) ■ Static Drive (IOH/IOL) ±24 mA @ 3.0V VCC ±18 mA @ 2.3V VCC ±6 mA @ 1.65V VCC ■ Uses patented noise/EMI reduction circuitry ■ Latch-up performance exceeds 300 mA ■ ESD performance: Human body model > 2000V Machine model > 200V ■ Packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

With the Output Enable (OEn) LOW, the contents of the flip-flops are available at the outputs. When OEn is HIGH, the outputs go to the high impedance state. Operations of the OEn input does not affect the state of the flip-flops. The 74VCX32374 consists of thirty-two edge-triggered flip-flops with individual D-type inputs and 3-STATE true outputs. The device is byte controlled with each byte functioning identically, but independent of the other. The control pins can be shorted together to obtain full 32-bit operation. Each clock has a buffered clock and buffered Output Enable common to all flip-flops within that byte. The description which follows applies to each byte.
