74HC/HCT541
Octal buffer/line driver; 3-state
FEATURES
• Non-inverting outputs
• Output capability: bus driver
• ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT541 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT541 are octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs OE1 and OE2. A HIGH on OEn causes the outputs to assume a high impedance OFF-state.
The “541” is identical to the “540” but has non-inverting outputs
QUICK REFERENCE DATA
GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns
| SYMBOL | PARAMETER | CONDITIONS | TYPICAL | UNIT | |
|---|---|---|---|---|---|
| HC | HCT | ||||
| tPHL/ tPLH | propagation delay An to Yn | CL = 15 pF; VCC = 5 V | 10 | 12 | ns |
| CI | input capacitance | 3.5 | 3.5 | pF | |
| CPD | power dissipation capacitance per buffer | notes 1 and 2 | 37 | 39 | pF |
Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V
