DESCRIPTION
The M54/74HC4094 is a high speed CMOS 8 BIT
SIPO SHIFT LATCH REGISTER fabricated with sili-
con gate C2MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
This device consists of an 8-bit shift register and an
8-bit latch with 3-state output buffer. Data is shifted
serially through the shift register on the positive
going transition of the clock input signal. The output
of the last stage (Qs) can be used to cascade sev-
eral devices.
Data on the Qs output is transferred to a second out-
put (Qs’) on the following negative transition of the
clock input signal. The data of each stage of the shift
register is provided with a latch, which latches data
on the negative going transition of the STROBE
input signal. When the STROBE input is held high,
data propagates through the latch to a 3-state output
buffer.
This buffer is enabled when OUTPUT ENABLE
input is taken high. All inputs are equipped with pro-
tection circuits against static discharge and transient
excess voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD VCC fIN + ICC/2 (per FLIP/FLOP)
