TC74HC40105AP Product details

Description

(1) Writing data Data can be written into the FIFO whenever DIR is high and a low to high transition occurs on the SI pin.DIR will toggle momentarily until the data has been transferred to the second word register.SI must be toggled before the next 4-bit word can be written.The first and subsequent words will automatically ripple to the output end of the device even if there is not a full 16 words of input data.When all 16 words are filled with data, DIR will go low and additional data canno.

Features

High speed: fmax 25 MHz (typ. ) at VCC = 5 V.
Low power dissipation: ICC = 4 μA (max) at Ta = 25°C.
High noise immunity: VNIH = VNIL = 28% VCC (min).
Output drive capability: 10 LSTTL loads for DIR, DOR 15 LSTTL loads for Q0 to Q3.
Symmetrical output impedance: |IOH| = IOL = 4 mA (min) for DIR, DOR |IOH| = IOL = 6 mA (min) for Q0 to Q3.
Balanced propagation delays: tpLH ∼.
tpHL.
Wide operating voltage range: VCC (opr) = 2 to.
