74LVTH244SJ集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

General Description

The LVT244 and LVTH244 are octal buffers and line drivers designed to be employed as memory address drivers, clock drivers and bus oriented transmitters or receivers which provide improved PC board density.

特性 Features

■ Input and output interface capability to systems at 5V VCC

■ Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH244), also available without bushold feature (74LVT244)

■ 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 244

■ Latch-up performance exceeds 500mA

■ ESD performance:

– Human-body model > 2000V

– Machine model > 200V

– Charged-device model > 1000V
