Functional Description

• Octal Bus Buffer

74HCT240D: INVERTED, 3-STATE OUTPUTS

74HCT244D: NON-INVERTED, 3-STATE OUTPUTS

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.

Their inputs are compatible with TTL, NMOS, and CMOS output voltage levels. The 74HCT240D is an inverting

3-state buffer having two active-low output enables. The 74HCT244D is non-inverting 3-state buffer the HCT244A

has two active-low output enables.

These devices are designed to be used with 3-state memory address drivers, etc.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

特性 Features

(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
