MC74VCX162374

The MC74VCX162374 is an advanced performance, noninverting 16bit Dtype flipflop. MC74VCX162374  is designed for very highspeed, very lowpower operation in 1.65V, 2.5V or 3.3V systems. The VCX162374 is byte controlled, with each byte functioning identically, but independently. Each byte has separate Output Enable and Clock Pulse inputs. These control pins can be tied together for full 16bit operation. When operating at 2.5V (or 1.65V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3V busses. MC74VCX162374  is guaranteed to be overvoltage tolerant to 3.6V.

The MC74VCX162374 consists of 16 edgetriggered flipflops with individual Dtype inputs and 3.6Vtolerant 3state outputs. MC74VCX162374 is designed with 26
series resistors in each of the outputs to reduce noise. The clocks (CPn) and Output Enables (OEn) are common to all flipflops within the respective byte. The flipflops will store the state of individual D inputs that meet the setup and hold time requirements on the LOWtoHIGH Clock (CP) transition. With the OE LOW, the contents of the flipflops are available at the outputs. When the OE MC74VCX162374 is HIGH, the outputs go to the high impedance state. The OE input level does not affect the operation of the flipflops.
