8-Line to 1-Line Data Selector/Multiplexer/Register
With 3-State Outputs
SCHS277D - November 1997 - Revised May 2003
Features
Description
• HC/HCT354
- Transparent Data and Select Latches
• Buffered Inputs
• Three-State Complementary Outputs
• Bus Line Driving Capability
• Typical Propagation Delay: VCC = 5V, CL = 15pF,
TA = 25oC
- Data to Output = 18ns
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
at VCC = 5V
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
VIL= 0.8V (Max), VIH = 2V (Min)
- CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH
The CD54HC354, CD74HC354, and CD74HCT354 are data
selectors/multiplexers that select one of eight sources. In both
types, the data select bits S0, S1 and S2 are stored in
transparent latches that are enabled by a low latch enable
input, LE.
In the HC/HCT354 the data enable input, E, controls
transparent latches that pass data to the outputs when E is
high and latches in new data when E is low.
In both types the three-state outputs are controlled by three
output-enable inputs OE1, OE2, and OE3.
