SN54BCT2240, SN74BCT2240 OCTAL BUFFERS AND LINE/MOS DRIVERS WITH 3-STATE OUTPUTS

SCBS030D - SEPTEMBER 1988 - REVISED APRIL 1994

features

• State-of-the-Art BiCMOS Design Significantly Reduces I_CCZ
• Output Ports Have Equivalent 33- Series Resistors, So No External Resistors Are Required
• 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
• Package Options Include Plastic Small-Outline (DW) and Shrink Small-Outline (DB) Packages, Ceramic Chip Carriers (FK) and Flatpacks (W), and Standard Plastic and Ceramic 300-mil DIPs (J, N)

description

These octal buffers and line drivers are designed specifically toimprove both the performance and density of 3-state memory addressdrivers, clock drivers, and bus-oriented receivers and transmitters.Taken together with the SN74BCT2241 and ´BCT2244, these devicesprovide the choice of selected combinations of inverting andnoninverting outputs, symmetrical active-low output-enable () inputs, and complementary OE and inputs. Thesedevices feature high fan-out and improved fan-in.

The ´BCT2240 is organized as two 4-bit line drivers withseparate output-enable ()inputs. When is low, thedevice passes data from the A inputs to the Y outputs. When is high, the outputs are in thehigh-impedance state.

The outputs, which are designed to source or sink up to 12 mA,include 33- seriesresistors to reduce overshoot and undershoot.

The SN54BCT2240 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74BCT2240 is characterized for operation from 0°C to70°C.
