DESCRIPTION

The 74ACT16374 is an advanced high-speed CMOS 16-BIT D-TYPE FLIP-FLOP (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

This 16 bit D-Type Flip-Flop is controlled by two clock inputs (CK) and two output enable inputs (OE). The device can be used as two 8-bit flip-flops or one 16-bit flip-flop.

On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs.

While the (OE) input is low, the outputs will be in a normal logic state (high or low logic level); while OE is high, the outputs will be in a high impedance state.

The output control does not affect the internal operation of flip-flops; that is, the old data can be retained or the new data can be entered even while the outputs are off.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED:

fMAX = 120MHz (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 8µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS

VIH = 2V (MIN.), VIL = 0.8V (MAX.)

■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 24mA (MIN)

■ OPERATING VOLTAGE RANGE:

VCC (OPR) = 4.5V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY
