Product Summary

The SN74ACT244DBR octal buffers/driver is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SN74ACT244DBR is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.

Parametrics

SN74ACT244DBR absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 7 V; (2)Input voltage range, VI: -0.5 V to VCC + -0.5 V; (3)Output voltage range, VO: -0.5 V to VCC + -0.5 V; (4)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (6)Continuous output current, IO (VO = 0 to VCC): ±50 mA; (7)Continuous current through VCC or GND: ±200 mA; (8)Storage temperature range, Tstg: -65℃ to 150℃.

Features

SN74ACT244DBR features: (1)4.5-V to 5.5-V VCC Operation; (2)Inputs Accept Voltages to 5.5 V; (3)Max tpd of 9.5 ns at 5 V; (4)Inputs Are TTL Compatible.
