8 / 9 page December 1990 8 Philips Semiconductors Product specification 3-to-8 line decoder/demultiplexer with address latches 74HC/HCT237 AC WAVEFORMS Fig.6 Waveforms showing the address input (An) and enable inputs (E2, LE) to output (Yn) propagation delays and the output transition times. (1) HC : VM = 50%; VI = GND to VCC . HCT: VM = 1.3 V; VI = GND to 3 V. Fig.7 Waveforms showing the enable input (E1) to output (Yn) propagation delays and the output transition times. (1) HC : VM = 50%; VI = GND to VCC . HCT: VM = 1.3 V; VI = GND to 3 V. Fig.8 Waveforms showing the data set-up, hold times for An input to LE input and the latch enable pulse width. The shaded areas indicate when the input is permitted to change for predictable output performance. (1) HC : VM = 50%; VI = GND to VCC . HCT: VM = 1.3 V; VI = GND to 3 V. |
