Datasheet Details

• Octal Bus Buffer 74HCT240D: INVERTED, 3-STATE OUTPUTS 74HCT244D: NON-INVERTED, 3-STATE OUTPUTS 2.

General The 74HCT240D, and 74HCT244D are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology.

They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

(1) Wide operating temperature range: Topr = -40 to 125.
(Note 1) (2) High speed: tpd = 13 ns (typ. ) at VCC = 5.5 V (3) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25.
(4) Compatible with TTL outputs: VIL = 0.8 V(max) VIH = 2.0 V(min) (5) Wide interfacing ability: LSTTL, NMOS, CMOS (6) Balanced propagation delays: tPLH ≈ tPHL Note 1: Operating Range spec of Topr = -40.
