TC74VHC157FK Overview
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It consists of four 2-input digital multiplexers with mon select and strobe inputs. When the STROBE input is held “H” level, selection of data is inhibited and all the outputs bee “L” level.
TC74VHC157FK Key Features
- High speed: tpd = 4.1 ns (typ.) at VCC = 5 V

- Power down protection is provided on all inputs
- Balanced propagation delays: tpLH ∼- tpHL
- Wide operating voltage range: VCC (opr) = 2 V to 5.5 V
- Low noise: VOLP = 0.8 V (max)
- Pin and function patible with 74ALS157
