Texas Instruments 74HCT240
The ’HC240 and ’HCT240 are inverting three-state buffers having two active-low output enables. The CD74HC241, ’HCT241, ’HC244 and ’HCT244 are non-inverting three-state buffers that differ only in that the 241 has one active-high and one active-low output enable, and the 244 has two active-low output enables.| Part No. | 74HCT240 |

FEATURES
● HC/HCT240 Inverting● HC/HCT241 Non-inverting
● HC/HCT244 Non-inverting
● Typical propagation delay = 8ns at VCC = 5 V, CL = 15 pF, TA = 25℃ for HC240
● Three-state outputs
● Buffered inputs
● High-current bus driver outputs
● Fanout (over temperature range) – Standard outputs: 10 LSTTL loads – Bus driver outputs: 15 LSTTL loads
● Wide operating temperature range: –55℃ to 125℃
● Balanced propagation delay and transition times
● Significant power reduction compared to LSTTL Logic ICs
● HC types: – 2 V to 6 V operation – High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5 V
● HCT types: – 4.5 V to 5.5 V operation – Direct LSTTL input logic compatibility, VIL = 0.8 V (max), VIH = 2 V (min) – CMOS input compatibility, II ≤ 1μA at VOL, VOH 2
