74V2T125CTR中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The 74V2T125 is an advanced high-speed CMOS DUAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

3-STATE control input nG has to be set HIGH to place the output into the high impedance state.

Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 3V to 5V systems and it is ideal for portable applications like personal digital assistant, camcorder and all battery-powered equipment.

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

■ HIGH SPEED: tPD = 3.8ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS: VIH = 2V (MIN), VIL = 0.8V (MAX)

■ POWER DOWN PROTECTION ON INPUTS AND OUTPUTS

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE: VCC(OPR) = 4.5V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY
