4 Bit × 16 Word FIFO Register
The TC74HC40105A is a high speed CMOS 4 bit × 16 word
first-in, first-out (FIFO) Strage Register fabricated with silicon
gate C2MOS technology.
It achieves the high speed operation while maintaining the
CMOS low power dissipation.
The device is capable of handling 16 four-bit words and it is
possible to handle the input and output data at different shifting
rates.
When the DATA-IN-READY (DIR) is high, data is written into
the registers by a low to high transition of the SHIFT IN (SI)
input. And when DATA-OUT-READY (DOR) is high, data is read
out of the registers by a high to low transition of the SHIFT
OUT ( SO ) input.
If the MASTER RESET (MR) is high, the DIR goes high and
DOR goes low. The data in the internal registers are not changed
but are declared invalid.
The TC74HC40105A can be cascaded to form longer registers
or wider words.
The DATA OUTPUTs (Qn) are 3-State Outputs. When
OUTPUT ENABLE ( OE ) is held high, the Qn’s are in high
impedance state.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
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 6 V
