Product Summary
The SN74AHC244DW octal buffers/driver is designed specifically to improve the performance and density of 3-state memory-address driver, clock driver, and bus-oriented receiver and transmitter. The SN74AHC244DW is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
Parametrics
SN74AHC244DW absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V; (2)Input voltage range, VI (see Note 1): –0.5 V to 7 V; (3)Output voltage range, VO (see Note 1): –0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI < 0): –20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (6)Continuous output current, IO (VO = 0 to VCC): ±25 mA; (7)Continuous current through VCC or GND: ±50 mA; (8)Package thermal impedance, θJA (see Note 2): DB package 70℃/W; DGV package 92℃/W; DW package 58℃/W; N package 69℃/W; NS package 60℃/W; PW package 83℃/W; (9)Storage temperature range, Tstg: –65 to 150℃.
