General Description
The LVT32374 and LVTH32374 contain thirty-two noninverting D-type flip-flops with 3-STATE outputs and are 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.
The LVTH32374 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
These flip-flops are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT32374 and LVTH32374 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
