SN74HC245PWLE

The SN74HC245PWLE is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The features of the SN74HC245PWLE are: (1)wide operating voltage range of 2V to 6V; (2)high-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads; (3)low power consumption, 80-A max ICC; (4)typical tpd=12ns; (5)±6-mA output drive at 5V; (6)low input current of 1A max.

The following is about the absolute maximum ratings of SN74HC245PWLE: (1)Supply voltage range, VCC: 0.5 V to 7 V; (2)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (3)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±35 mA; (5)Continuous current through VCC or GND: ±70 mA; (6)Package thermal impedance, qJA: DB package 115°C/W, DW package 97°C/W, N package 67°C/W, PW package 128°C/W; (7)Storage temperature range, Tstg: 65°C to 150°C.

The electrical characteristics of the SN74HC245PWLE are: (1)VOH: 1.9 min at VI=VIH or VIL, IOH=-20A, VCC=2V; (2)VOL: 0.1V max at VI=VIH or VIL, IOL=20A, VCC=2V; (3)II: ±1000nA max at VI=VCC or 0, VCC=6V; (4)IOZ: ±5A max at VO=VCC or 0, VCC=6V; (5)ICC: 80A max at VI=VCC or 0, IO=0, VCC=6V; (6)Ci: 10pF max at VCC=2V or 6V.
