Характеристики
SN74HCT244N PDIP20The SN74HCT244N is an Octal Buffer and Line Driver designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers and bus-oriented receivers and transmitters. The HCT244 device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When (OE) is low, the device passes non-inverted data from the A inputs to the Y outputs. When (OE) is high, the outputs are in the high-impedance state.
• 3-state outputs drive bus lines or buffer memory address registers
• High-current outputs drive up to 15 LSTTL loads
• Inputs are TTL-voltage compatible
• 80µA Maximum low power consumption ICC
• 13ns Typical tpd
• ±6mA Output drive at 5V
• 1µA Maximum low input current
