低电压八路D型触发器带3态输出 Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The LVT374 and LVTH374 are high-speed, low-power octal D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. A buffered Clock CP and Output Enable OE are common to all flip-flops.
The LVTH374 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
Features
■ Input and output interface capability to systems at 5V VCC
■ Bus-Hold data inputs eliminate the need for external pull-up resistors to hold unused inputs 74LVTH374, also available without bushold feature 74LVT374
■ Live insertion/extraction permitted
■ Power Up/Down high impedance provides glitch-free bus loading
■ Outputs source/sink –32mA/+64mA
■ Functionally compatible with the 74 series 374
■ Latch-up performance exceeds 500mA
■ ESD performance:
– Human-body model > 2000V
– Machine model > 200V
– Charged-device model > 1000V
