1 / 5 page Philips Semiconductors Product specification 74LVT2241 3.3V Octal buffer/line driver with 30 W series termination resistors; 3-State 1 1996 May 29 853-1840 16867 FEATURES • Octal bus interface • 3-State buffers • Output capability: +12mA/-12mA • TTL input and output switching levels • Input and output interface capability to systems at 5V supply • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs • Power-up 3-State • Live insertion/extraction permitted • No bus current loading when output is tied to 5V bus • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model. • Outputs include series resistance of 30Ω, making external termination resistors unnecessary. DESCRIPTION The 74LVT2241 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74LVT2241 device is an octal buffer that is ideal for driving bus lines. The device features two Output Enables (1OE, 2OE), each controlling four of the 3-State outputs. The 74LVT2241 is designed with 30 Ω series resistance in both the High and Low states of the output. This design reduces the line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters.
