74LVTH244

74LVT244, 74LVTH244 — Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs January 2008 74LVT244, 74LVTH244 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs 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 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. The LVTH244 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These octal buffers and line drivers are designed for lowvoltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT244 and LVTH244 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
