SN54HC240, SN74HC240 SCLS128G – DECEMBER 1982 – REVISED APRIL 2022 SNx4HC240 Octal Buffers and Line Drivers With 3-State Outputs 1 Features 2 Description • • These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The ’HC240 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. • • • • • Wide Operating Voltage Range of 2 V to 6 V High-Current Outputs Drive Up To 15 LSTTL Loads Low Power Consumption, 80-µA Max ICC Typical tpd = 9 ns ±6-mA Output Drive at 5 V Low Input Current of 1 µA Max 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers Device Information (1) PART NUMBER PACKAGE BODY SIZE (NOM) SN74HC240DW SOIC (20) 12.8 mm × 7.50 mm SN74HC240DBR SSOP (20) 7.2 mm × 5.30 mm SN74HC240N PDIP (20) 25.40 mm × 6.35 mm SN74HC240NSR SO (20) 15.00 mm × 5.30 mm SN74HC240PW TSSOP (20) 6.50 mm × 4.40 mm SN74HC240J CDIP (20) 26.92 mm × 6.92 mm SNJ54HC240FK LCCC (20) 8.89 mm × 8.45 mm SNJ54HC240W CFP (20) 13.72 mm × 6.92 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.

Each VCC terminal should have a good bypass capacitor to prevent power disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results. 9 Layout 9.1 Layout Guidelines When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such unused input pins must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. All unused inputs of digital logic devices must be connected to a logic high or logic low voltage, as defined by the input voltage specifications, to prevent them from floating. The logic level that must be applied to any particular unused input depends on the function of the device. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic function or is more convenient.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 10.6 Glossary TI Glossary 10 This glossary lists and explains terms, acronyms, and definitions.
