DESCRIPTION

The 74ACT16244 is an advanced high-speed CMOS 16-BIT BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

G output control governs four BUS BUFFERs.

The device is designed to be used with 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels.

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

■ HIGH SPEED: tPD = 4.8ns (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
