INTEGRATED CIRCUITS 74LVT244B 3.3V Octal buffer/line driver (3-State) Propduct specification IC23 Data Handbook 1998 Nov Philips Semiconductors Philips Semiconductors Product specification 3.3V Octal buffer/line driver (3-State) 74LVT244B FEATURES Octal bus interface 3-State buffers Speed upgrade of 74LVTH244A Output capability: +64mA/-32mA 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 DESCRIPTION The LVT244B is a high-performance BiCMOS product designed for VCC operation at 3.3V. This device is an octal buffer that is ideal for driving bus lines. The device features two Output Enables (OE1, OE2), each controlling four of the 3-State outputs. 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 QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN COUT ICCZ PARAMETER Propagation delay nAx to nYx Input capacitance Output capacitance Total supply current CONDITIONS Tamb = 25°C; GND = 0V CL = 50pF; VCC = 3.3V VI = 0V or 3.0V Outputs disabled; VO = 0V or 3.0V Outputs disabled; VCC = 3.6V TYPICAL 1.9 2.0 4 8 0.13 UNIT ns pF pF mA ORDERING INFORMATION PACKAGES 20-Pin Plastic SOL 20-Pin Plastic SSOP Type II 20-Pin Plastic TSSOP Ty...
